Flow Cytometry Protocol:
Day Before:
- Start overnight cultures of your strains to be tested in 5-10ml SD Complete media. (Do not use YPD. YPD has fluorescence background which would cause problems for FACS testing.)
Day Of:
Flow Procedures:
- Dilute overnight cultures 1:100 in the 96 well shaker plate. (Shaker plates can be found in the Lim Lab in the back glass cabinet where large glass bottles can also be found.)
- Allow cells to enter growth stage by putting on plate shaker at 30°C going 1000rpm (found in Flow room or the 30°C room in the other hall)for 2-3 hours after dilution.
- Induce with alpha factor. The stock alpha factor in the freezer is 3mM and we use it at the final concentrations of: 0, 1nM, 10nM, 100nM, and 1uM.
- Allow introduction to proceed on plate shaker for 90 min to 2 hrs, no longer.
- Transfer 250ul of each culture to the 96 well flow cytometry v-bottom plate. (found in flow room on shelf) Arrest cells with 10ul of cycloheximide. (stops translations of proteins; stops growth)
- Run on flow cytometer.
- Analyze Data.
Things to check for Flow:
- Check that machine is on standby and not run. (Should be on standby when not in use)
- Make sure that a clean plate has been ran by the person before you. Otherwise, run a clean plate. (A1-A4 bleach, B1-B4 water)
- Check fluid buffer box and storage tanks. Discard waste fluid in sink 2 doors down (remember to add bleach to tank when done) and replace buffer box if needed.
- Make sure you have a positive and negative control so that you can set the parameters.
- Open up FACSDiva. Sign into iGEM account.
- Create new FACS experiment. Highlight needed wells and use the blue button to create wells for use. Create specimens among the wells and rename them.
- Open up inspector to check parameters.
- Run well. (Do not click 'Run Plate'.)
- Once finished, export data onto a USB.
- Run a clean plate.

Using Flowjo and Matlab to Analyze Data
Flowjo:
- Export Data from USB and transfer to iGEM2014 folder.
- Open Flowjo and drag data over to box.
- Set an appropriate gate.
- Go to data, select all data and press 'Σ'. Select median, mean, and count.
- Press the refresh button. Additional numerical data should be present.
Matlab:
- Open up a new script. and comment the title of the script. (Use '%' for comments.)
- Enter the alpha factor info that will serve as the x-axis. (Put in log form.)
- Enter the yGEM data. This will serve as the y-axis.
- Type your figure info and press the "go".
Example of Matlab script to create graphs based on Flowjo Data:
%14-6-19 Alpha-Factor Promoter ASG7
clear % this will get rid of all previous graphs
Clear all % same as above but for ALL graphs
alpha = [0 1 10 100 1000] % nanomolar nM, spaces show a new number
alpha = [0.01 1 10 100 1000] % 0.01 is really 0. Flowjo cannot comput 0s
yGEM = [558 715 1040 2230 4731] %mean GFP C1-C5 ASG7
figure(1)
semilogx(alpha,yGEM4,'--c'), %('--c') means dotted line, cyan colored line, and star for points.
hold on
xlabel'alpha') % [] denotes concentration, () denotes "in"
ylabel('mean GFP (au)') % au means arbitrary unit
title('Alpha-factor vs mean GDP yGEM4')
legend('yGEM4')
axis([0.01 1500 200 4000]); % axis([xmin xmax ymin ymax])

- PRM2
- Negative Control (heated at 55°C for 40 min due to being made late)
ALWAYS MAKE A NEGATIVE CONTROL!
- Jessica did a Colony PCR for rtTA Promoters and a Miniprep for the 1st Transformation.
07/03/14
Results of Re-Transformtation of Inducible Promoters + GFP
- Few to no colonies grew onthe transformed plates, which leads me to think that the Gibson Assembly failed because only PRM2 worked and was Gibson'ed prior to the other transformed promoters.
PRM2 grew many tiny colonies.
Promoter Colonies PRM2 TMTC PCL2 2 PRM6 3 PRM3 2 YDR124W ~ 40 PRM1 0 ECM18 0 HYM1 0 Neg Ctrl 0
Possible Explanations for Failure:
- Gibson Assembly failed due to bad Gibson Master Mix
- Backbone concentrations were not high enough, which would make sense because PRM2 had a new backbone which had a higher concentration than the rest of the promoters.
- PRM2 Backbone Concentration: 208.7 ng/ul
Backbone Digestion
- Jessica remade the backbones, but the concentrations are still very low.
- Used the minipreps from my box in the -20°C fridge.

Colony PCR Gel of Transformation #3:
07/11/14
Miniprep of Transformation #3
- Made cultures of the the transformations.
Sent Transformation #3 into sequencing.
07/14/14
Results of Sequencing and Colony PCR
PCR showed that rtTA and GFP were both present.
Sequencing showed that GFP was in the backbone, not rtTA
- rtTA was probably not in the backbone and was floating near the colonies instead, so when we picked up the colonies for Colony PCR, we also picked up the rtTA with them.
- Will use Backbone set #2 in Jessica's box along with Derrick's PRM1 and PRM2 backbones from 6/09/14.
- Will use the new inserts from 7/11/14 in my box.

|Inserts (200ng each) | x ul |
|Linear Cloning Vector (50ng each)| y ul |
|GeneArt 2X Enzyme Mix | x+y ul |
- In a microcentrifuge tube, set up the seamless cloning and assembly reaction. It is CRUTIAL that you add the GeneArt 2x Enzyme Mix as the LAST COMPONENT.
- Quickly thaw the GeneArt 2x Enzyme Mix on ice and pipette up and down to mix thoroughly. Add (x+y) ul of thawed enzyme. Mix to each reaction. Immediately return GeneArt 2x Enzyme Mix to -80°C Freezer.
- Mix the reaction components completely by pipetting up and down SLOWLY 3 times and then gently tap the side of the tubed 3-5 times to mix.
- If needed, briefly centrifge (< 500rpm for < 5sec) to collect reaction components to the bottom of the microcentrifuge tube.
- Incubate the reaction mix at room temperature for 15-30 min. Do not incubate longer than 30 min!
- After incubation is complete, plate the reaction mix on ice for 2-5 min before proceeding to transformation step. Do not let the samples stay on ice for more than 5 min before transformation.
Transformation:
- Use 3ul of the seamless cloning and assembly reaction to transform NEB5α cells. Do not use electrocompetent cells.
- Follow normal Transformation procedures.
- Add 25ul Competent Cells to 10ul Gibson Mix. (ADD ON ICE)
- Incubate on ice for 30 min.
- Incubate at 42°C for 45 sec.
- Incubate on ice for at least 2 min.
- Add 250ul SOC Media (Make sure it isn't cloudy) to cells.
- Shake in 37°C Incubator Room for 1 hr. (Warm plates also)
- Plate on LB-CARB and keep in drawer over the weekend.
Miniprep of Transformations (PRM2, PRM6, SAG1)
- Used cultures made on 7/18/14 (put in incubator on 7/20/14)
Miniprep Precedure:
- Obtain E.Coli Cultures from 06/16/14 in 37°C Incubation Room.
- Resuspend pelleted bacterial cells in 250 µl Buffer PI and transfer to a microcentrifuge tube.
- Add 250 µl Buffer P2 and gently invert tube 4-6 times to mix. DO NOT VORTEX.
- Add 350 µl Buffer N3 and invert immediately 4-6 times.
- Centrifuge for 10 min at 13,000 rpm.
- Add supernatant to QIAprep spin column.
- Centrifuge for 30-60s - Discard flow through.
- Wash QIAprep spin column by adding 0.5 ml Buffer PB and centrifuging for 30-60s - Discard flow through.
- Wash column by adding 0.75 ml Buffer PE and centrifuginh for 30-60s
- Discard flow through and centrifuge for an additional 1 min to remove residual wash buffer.
Place column in clean 1.5 ml microcentrifuge tube. To elute DNA add 50 µl water or buffer EB, let stand for 1 min and centrifuge for 1 min.

Seamless Transformation from 7/21/14

Possible Explanations:
- Used wrong inserts
- Seamless went wrong
- Mutations of template
- Backbones not digested properly (not likely)
- PRM1 and PRM2 backbones have GFP
- Concentrations of both insert and backbone too low
Final Concensus: We will use another method to transform the cells:
- Instead of using Gibson or Seamless, we will PCR with primers for all 7kb.
- Currently ordering primers.
Meanwhile, transformations from 7/18/14 worked - colonies grew for all plates
- will attempt colony PCR to determine the presence of rtTA
- plates to be PCR'ed: PRM3, ECM18, YDR124W, CLG1, ASG7, HYM1, and PCL2
- plates to be excluded: PRM1 and PRM2 (both backbones have GFP), PRM6 (has both mutation and rtTA, determined by previous sequencing), SAG1 (backbone has GFP but has recently been redigested), '+' control, '-' control
Culturing pGEM #1-11 (except pGEM7) to make pGEM for backbone digestion tomorrow.

Prepared cultures of CB008DB Const+rtTA+GFP+mfa+pPCL2+mCherry M3, M6, M7, and M10 to be ran on the following day to confirm the presence or lack of presence of RFP.
pTEF1 missing, may need to grow a glycerol stock streak plate of it.

CB008DB Const+rtTA+GFP+mfa+pPCL2+mCherry Run
- Shaker plate not completely clean, I attemped to clean it out with water. Saw chunks of dried cells on the bottom of some of the wells. MAKE SURE YOU PUT THE SHAKER PLATE IN THE BLEACH BIN AFTER USE!!!
- M10 may be contaminated due to the shaker plate.
- M6 culture was not labeled correctly in the incubator shaker, M6 may not actually be the right specimen.
Ran 2 time points: 0 hr and 5 hrs.
- Data to be analyzed in the near future after asking Ianto how to run only two time points.

Successfully ran all the plates.
09/10/14
Data Analysis of Co-culture of CB008 Const+rtTA+GFP+mfa+pAGA+mCherry Run
- After running the data on FlowJo and Matlab, we compared the data to the original pAga1+mCherry pTEF1, M7, and M10 data.
The comparison showed slight variation and unexpected results.
- Maybe due to the larger cells being too stressed from producing so many proteins, and the overall population producing less as a result of this.
After comparing the data, it was decided that the best option would be to rerun this experiment but with pTEF1, M7, and M10 separately put on the plate as a comparison.
Started growing cultures of pTEF1, M7, and M10 in the incubator.

Did not make a co-culture of pTEF1+M10 because the two promoters are too close in activity to make much of a difference.
09/12/14
Attempt of Co-Culture CB008 Const+rtTA+GFP+mfa+pAGA1+mCherry Round 2 Run
- Cancelled due to wrong culture being grown and due to the absence of induction.
- Make sure that Eleanor and George pay attention when growing cultures and when inducing with doxycycline.
- pPCL2 was grown instead of pAGA1. pPCL2 cannot be used in a co-culture due to its lack of RFP.
Experiment to be continued at another time.

09/18/14
Data Analysis of AFRP+rtTA+GFP+mfa+pAGA+mCherry Run
Ran the data on FlowJo and Matlab.
- Got interesting results like bimodal populations and large amounts of noise.
Eleanor's Transformations
Assisted Eleanor in her transformations of CB008 M3 and M6 with pTET+mfa, pAGA1+mCherry, and pPCL2+mCherry.
- None of her transformations worked other than M3+mfa which had 2 colonies. I put the plates back into the incubator in case they worked.
Made cultures of M3+rtTA and M6+mfa to re-transform the following day.
09/19/14
Results of Eleanor's Transformations
Plates that grew colonies:
- CB008 M3 pAGA1+mCherry = 1 colony
- CB008 M3 mfa = 2 colonies
CB008 M6 mfa+pPCL2+mCherry = 4 colonies
Will do a Colony PCR to check plates - unlikely that plates worked
Linearized plasmids: mfa and pAGA1+mCherry
Kara advises us to not used previously linearized plasmid.
- will attempt to use Jeffret's digested pPCL2+mCherry for M6.
Re-transformed and put into incubator:
- CB008 M3+mfa
- CB008 M3+pAGA1+mCherry
- CB008 M3+mfa+pAGA1+mCherry
- CB008 M6+mfa+pAGA1+mCherry
- CB008 M6+mfa+pPCL2+mCherry
9/22/14
Colony PCR of Transformations
Ran colony PCR's of the Transformations from 9/19 and 9/15 of the CB008 Constitutive Promoters.
Checked for mfa and pPCL2/pAGA1+mCherry separately.
Colony PCR Gel: (Eleanor said that M6 already has mfa even if there is no band)
09/25/14
PCR Amplification of Bar1, mfa, and pGEM1-16 (except 7 and 10)
Due to the primers not covering all of the needed insert parts, new primers with new overhangs were ordered. I was put in charge of PCR amplifying the plasmids with these new primers.
Used primers #103-110.
mfa Template: Shuaixin's PRM2 + mfa (7.606) Plasmid
Bar1 Template: Shuaixin's PCL2 + Bar1 (6.62) Plasmid
George did the PCR for Ste2.
Used Seamless to transform all the plasmids. George made a pGEM10 PCR insert, which I used for transformation.
Used pSB1C3 as backbone. Used cleaned up undigested one.
09/26/14
Results of Transformation
All the pGEM plates transformed very well.
Bar1, Ste2, and mfa did not transform very well.
Negative control grew for some reason also, hopefully because of a contamination of PCR product.
Colony PCR of Transformation
After a few more hours of growing in the incubator, Bar1, Ste2, and mfa grew more cells.
Did a colony PCR on all the plates (3 colonies from each plate) (a total of 62 Colony PCRs including 5 colonies of Eleanor's Bar1 Transformations)
Jeffrey ran the gel for my Colony PCR.
Colony PCR Gel:
09/28/14
I moved to UC Davis and will be taking a break from lab work to concentrate on classes.
Kara made cultures from the plates for the successful Colony PCR's to miniprep on Monday.
09/29/14
Miniprep of Cultures
Eleanor did the miniprep of the cultures from 9/28/14 and sent them into sequencing.
09/30/14
Results of Sequencing
Sequencing showed that the miniprep was wrong. May have to redo everything or pick new colonies off the plates? Need to discuss with Kara on this matter.

Flow Cytometry of AFRP + GFP
Overnight cultures of CB008+AFRP+GFP diluted ~100x (to a final concentration of OD600 0.5-0.1, Saturated overnight cultures should be OD600 of ~7) in SD complete media, and grown for 3 hours, 1000rpm shaker, 30ºC. Growing in 2mL well plates
Induce with Alpha-factor. Stock is in 3mM. Final concentrations are 0, 1nM, 10nM, 100nM, 1000nM. Alpha-factor cannot be refrozen, so throw leftover away.
Induce for 90mins, but no longer than 120mins
Transfer 250u of each well into a V-bottom 96-well plate containing 10ul of the fixing chemical Cyclohexamide. (thats 4 ul for every 100ul of culture) Cyclohexamide stops protein production by inhibiting ribosomes.
Run on the flow cytometer.

Instructions for starting flow:
- Turn on and wait 30mins for the machine to warm up
- Re-initialize the HTS, them prime it three times. You'll get a bubble in the lines if you don't
- Run CST!!! Follow the sheet in front of the monitor for more instructions for that part. (CST uses beads to calibrate the laser detection.) add one drop into 250ul of sheath fluid in A1.
- Bead LOT ID: use the one that is most current
- Load A1-A4 with bleach and B1-B4 with water [flip for the opposite corner] -Cytometer>CST. Make sure cytometer performance results passed
Run Clean Plate: 1. Click on experiment. Experiment>Open experiment 2. Open clean plate "Daily Clean" - 96 well U-bottom" 3. Be here to see if the cleaning is going correctly, low events (less than 100events/sec for bleach and less than 10events/sec for water) 4. If over the events, run another clean plate 5. View events in aquisition dashboard in view>Acquisition dashboard 6. Can also make a clean plate using HTS>Clean

Flow Cytometer Notes
Overnight cultures of CB008+AFRP+GFP diluted ~100x (to a final concentration of OD600 0.5-0.1, Saturated overnight cultures should be OD600 of ~7) in SD complete media, and grown for 3 hours, 1000rpm shaker, 30ºC. Growing in 2mL well plates
Induce with Alpha-factor. Stock is in 3mM. Final concentrations are 0, 1nM, 10nM, 100nM, 1000nM. Alpha-factor cannot be refrozen, so throw leftover away.
Induce for 90mins, but no longer than 120mins
Transfer 250u of each well into a V-bottom 96-well plate containing 10ul of the fixing chemical Cyclohexamide. (thats 4 ul for every 100ul of culture) Cyclohexamide stops protein production by inhibiting ribosomes.
Run on the flow cytometer.
Flow Cytometer things to remember:
- check the sheath fluid box to see if its empty
- check the waster container. If full, dispose and add new bleach
- take care not to leave the machine on run. Save sheath fluid by keeping on standby when not in use
- find parameters using negative controls. (FSC, SSC, Fluorescense marker)
- DO NOT RUN PLATE. RUN WELLS instead. (Run the first well by itself first b/c it needs time to create file folders.) this causes problems.
- Run plate only saves data of the first well.
- Can rerun through the first well again which would suck up air. Air no good for the machine.
- highlight wells and change settings on the right in the aquisition dashboard screen
- mixing speed 180ul/sec
- mix 3 times rather than 2
- run at 1ul/sec for samples and 0.5ul/sec for negative controls when finding parameters.
- make sre uL doesn't exceed samle to prevent sucking up air. (Rule of thumb is to run 50ul less than allotted sample sizes for wells.)
Voltage settings were gotten by running negative controls and adjusting to readouts seen in histogram form of FSC, SSC, FITC

Transformation of pHY4 + AFRP
#7 ⎫
#9 | Grew at least a few colonies so they did okay
#13 ⎭
The rest, 1,2,5,6,8 didn't grow likely because of our low yield template promoter DNA. We need to restart and PCR promoters again for higher yield DNA. Then ligate and transform
Yesterdays AFRP PCR yields:
#4 84.35 ng/ul
#7 134.3 ng/ul
#10 84.14 ng/ul
#11 91.99 ng/ul
#12 64.64 ng/ul
Miniprepped cultures of Mach1 with pHY4 to get more pHY4 template.
*The PE buffer we used previously did not contain ethanol which was why we were having low yields for minipreps and other purifications.

* Always want excess RE
1) add 1ul ApaI, incubate at room temp for 2 hours
2) add 1ul of Xho1, incubate at 37ºC for 1 hour
Ran the backbone digest through a gel.
The streaks of pHY4 suggests that its been cut up by other nucleases so we can't purify this as our backbone. So we created overnight cultures of Mach1+pHY4 and are sequencing leftover digested phy4 to see if we have the backbone we want.
Created overnight cultures of the transformations that seemed to work: 7,9,13
Tomorrow we will miniprep and purify the construct for promoter testing.

Transformed 1,2,4,6,7,10,11,12, and negative control. The negative control grew colonies so the backbone may have liated back by itself so we are using phosphitase to remove phosphates so that it cannot ligate together.
They then colony PCRed and sequenced.

Also transformed the 2 AFRP+GFP that didnt work last time HYM1 (08/DB) & PRM3 (DB)
Made overnight cultures of the strain CB008+AFRP to test in on the flow after induction with 5 alpha-factor concentrations (0nM, 10nM, 1000nM, 10,000nM, 100,000nM)
Thurs 14/06/19
Overnight cultures of CB008+AFRP+GFP diluted ~100x (to a final concentration of OD600 0.5-0.1, Saturated overnight cultures should be OD600 of ~7) in SD complete media, and grown for 3 hours, 1000rpm shaker, 30ºC. Growing in 2mL well plates
Induce with Alpha-factor. Stock is in 3mM. Final concentrations are 0, 1nM, 10nM, 100nM, 1000nM. Alpha-factor cannot be refrozen, so throw leftover away.
Induce for 90mins, but no longer than 120mins
Transfer 250u of each well into a V-bottom 96-well plate containing 10ul of the fixing chemical Cyclohexamide. (thats 4 ul for every 100ul of culture) Cyclohexamide stops protein production by inhibiting ribosomes.
Run on the flow cytometer.
Flow Cytometer things to remember:
- check the sheath fluid box to see if its empty
- check the waster container. If full, dispose and add new bleach
- take care not to leave the machine on run. Save sheath fluid by keeping on standby when not in use
- find parameters using negative controls. (FSC, SSC, Fluorescense marker)
- DO NOT RUN PLATE. RUN WELLS instead. (Run the first well by itself first b/c it needs time to create file folders.) this causes problems.
- Run plate only saves data of the first well.
- Can rerun through the first well again which would suck up air. Air no good for the machine.
- highlight wells and change settings on the right in the aquisition dashboard screen
- mixing speed 180ul/sec
- mix 3 times rather than 2
- run at 1ul/sec for samples and 0.5ul/sec for negative controls when finding parameters.
- make sre uL doesn't exceed samle to prevent sucking up air. (Rule of thumb is to run 50ul less than allotted sample sizes for wells.)
Voltage settings were gotten by running negative controls and adjusting to readouts seen in histogram form of FSC, SSC, FITC

Instructions for starting flow:
- Turn on and wait 30mins for the machine to warm up
- Re-initialize the HTS, them prime it three times. You'll get a bubble in the lines if you don't
- Run CST!!! Follow the sheet in front of the monitor for more instructions for that part. (CST uses beads to calibrate the laser detection.) add one drop into 250ul of sheath fluid in A1.
- Bead LOT ID: use the one that is most current
- Load A1-A4 with bleach and B1-B4 with water [flip for the opposite corner] -Cytometer>CST. Make sure cytometer performance results passed
Run Clean Plate: 1. Click on experiment. Experiment>Open experiment 2. Open clean plate "Daily Clean" - 96 well U-bottom" 3. Be here to see if the cleaning is going correctly, low events (less than 100events/sec for bleach and less than 10events/sec for water) 4. If over the events, run another clean plate 5.

Meeting with Anusuya:
- Site directed mutagenesis of ribosome binding sites to fine tune expression of proteins. Tune down the effect of the promoters
- Two promoters back to back to increase expression?
- Find out how to differentiate yeast strains when they are co-cultured.
- Maybe work more with constitutive rather than the inducible because there might be variable behaviors and its hard to model.
- Email ben and ask for code from last year.
- Start modeling progress, promoters and outputs. Co-opt code that was written last year
- Flow with Bar1 deleted yeast.
- Find examples of Tcells that start out with slightly different inputs that strongly converge over time. Chaotic phenomenon.
- look up Chaotic phenomenon in immune cells.

Dilutions: 3 hour incubation with 100x dilutions in 2mL well plates. 9:35am -> 12:35pm
Added Alpha-factor. There are several possible mistakes when inducing. On 2-3 of the wells of the 100nm and 1000nm concentration, alpha factor was on the walls of the plate and may not have been added to the culture fully. Also, when using the multi-dispenser, the initial 10ul doesnt all fall off the tip, leaving residual liquid hanging. 12:50 -> 2:20pm

Group Meeting at 1pm Until then, everyone was working on their powerpoints for the presentation.
~3:00pm Colony PCR of CB008/CB008DB (+Constitutive Promoters +rtTA) (+pTET +GFP) 3 colonies of each were patched and PCRed onto URA knockout plates.
PCR Reaction:
10ul 2x GoTaq Mix
3ul ddH2O
1ul FW primer 606V2 (primers check for chromosomal integration at the URA2 site)
1ul RV primer 606V2
5ul boiled Template in 20mM NaOH
PCR Protocol:
95ºC 5mins
95ºC 30secs |
50ºC 30secs | x30
72ºC 1min |
4ºC hold
Running colony PCR on a gel tomorrow.
Tues 14/07/15
1). Running 24 colony PCRs. Expected band size is 940bp.
Gel Photo:
2). 6 Strains worked, the two that didn't are CB008DB+pTEF1+rtTA and CB008DB+m10+rtTA
3). We are redoing colony PCR of those 2 strains that failed, each with 5 colonies each this time. Update: Second colony PCR did not work so we will be doing a third colony PCR
Gel Photo:
4). Redoing Colony PCR for a third time, 5 colonies each again. This time we included 2 positive controls to check if the PCRs are at fault. If this doesn't work we will have to redo transformations for these two and we will most likely not run the DB strains on the flow tomorrow.
Update: Colony PCR did not work.

4). Yesterday's flow plate was contaminated and our data is very weird. (refer to Ianto's lab notebook on the same date) We will be redoing that experiment so today we should make more cultures for flow tomorrow.
Thu 14/07/17
Anusuya meeting: We should have everyone create a labnotebook/blog of what they do everyday so that we can keep track of everything. Background of T-cell signalling. Need good examples of what naturally happens. We need a specific thing we want to focus on and model for our project.
Read: 1). interaction between T-reg cells and T-helper cells. How T-reg with macrophages, their interaction represent some negative feedback. Macrophage somehow suppresses T-regs. 2). T-reg, dentridic cells. relates to neural. Stanford 2010, interaction btwn T-reg, T-helper, Th1-th2. 3). Topic of Neural information? microglia interaction? Might play a role in recruiting and regulating T-cells when there is injury to the brain.
1). Read some wiki and review papers, dont need data papers be able to understand whats going on with these interactions so that we have many examples where interactions play important roles.
2). Look from a non-immune viewpoint. There are interactions beyond the immune system so look into those and come up with examples. Perhaps we can build on the work from UCSF iGEM 2010.
3). COME UP WITH EXAMPLES, need an elavator pitch. Whats still unknown about these cell types? and how does this model we are making with yeast help us to understand whats going on. Specific termonology. Have some slides with these examples set up for the next meeting. Layout a rational.
4). Look up alpha factor diffusion rates. Delegate tasks for all of these points.
5). Have a point person for the medal requirements. Need someone to keep track of everything.
6). Maybe dedicate a 10min session to brief everyone about what has been done for the day and the end of every day. Have it written day and keep it in a text file for people to access.
7). Folders for all our files should be put into folders for the wiki. Update them! Intellecutal material, protocols, etc.
8). Create a library of motifs we've constructed and explain how its valuable. Find examples of them where they exist in the immune system.
Type 2 restriction sites. AAR1 BSA1
Modeling: Write code for both strains and their find out their output of alpha-factor. Then have both sets of code and add them together to see RFP output when those two cells are together.
factors to account for the model: diffusion constants, degredation rate, cell density (later)
Overnight cultures of CB008DB+pTET+GFP grew well. Continuing to tranform m10+rtTA. Diluted 20x at 9:45am -> 11:45am

~23 primers are coming in to clone AFRP upstream of BAR1 and Ste2 separately.
Note: 1. PCL2+mCherry in HY130 backbone is being constructed by Robert. We will probably make additional strains with this in place of pAGA+mCherry. 2. Jeffrey is working on getting m3+rtTA into CB008DB +pTET+GFP.
Mon 14/07/28
Last friday, Eleanor transformed mCherry into 6 strains with Constitutive Promoter, GFP, Alpha factor. Today I am colony PCRing them along with 3 other strains that have other things being integrated: 1) +rtTA for the m3s 2) +mfalpha for DB pTEF1 & m10.
Next steps: 1. Need to retransform DB m10 and CB008 m7 because they have no colonies. 2. Need to make glycerol stocks of the ones that worked for Colony PCR 3. For tomorrow, make cultures for tomorrow's flow (9 strains + control)
Auxotrophic marker Colony PCR primer names: His: FW RA145(#87) & REV RA146(#89) Trp: FW RA145(#87) & REV

time course flow allows us to create a stocastic model of our products: rtTA, GFP, alpha-factor, RFP.
Colony PCR2 redo from yesterday because only 1 worked
Constitutive Promoter Constructs progress:
Today George and I are retransforming:
- CB008DB+pTET+GFP+m3+rtTA[+pTET+mfalpha]
- CB008+pTET+GFP+m7+rtTA+pTET+mfalpha[+pAGA+mCherry]
- CB008+pTET+GFP+m10+rtTA+pTET+mfalpha[+pAGA+mCherry]
The salmon sperm boiled down to about 5ul for all 3 transformations. It also seemed a little viscous.
CB008+pTET+GFP+m10+rtTA+pTET+mfalpha[+pAGA+mCherry] already exists so our transformation of this (#3) was pointless. What we meant to do was CB008DB+m10+rtTA+pTET+GFP[+pTET+mfalpha]
After all our colony PCRs for the day, this is the update of the excell progress sheet:
Made cultures of all 10 things on the Consti list. 9 for transformations and 1 for glycerol stock.
Made cultures for tomorrows flow.
Weds 14/07/30
None of the cultures for today's flow grew. Only the controls grew. Looking back at the URA knock out patch plates that we inoculated from, they didn't grow very well. I think they moreso had a hard time growing than it not being correctly transformed because they came back positive in the colony PCRs (14/7/15). I transferred them onto a YPD patch plate to see if they would grow.
Derrick and I plated on YPD CB008/DB strains with pTET+GFP+consti+rtTA because the current patch plate on URA of CB008s does not have good growth. Cultures made from this patch plate did not grow either so holding out flow back.
Jeffrey and George are retransforming the ones that failed.
Thurs 14/07/31
Our steak plates of CB008/DB +pTET+GFP+Consti+rtTA over grew only on CB008DB. All the CB008s did not grow and have no sign of growth. This may mean that we will have to retransform consti+rtTA into our CB008 strains. So far, our glycerol stocks have not been working well for us; we don't know what the problem is.
Worked on the Explo powerpoint today.
Fri 14/08/01
Made streak plates with Derrick of everything we have so that we have fresh/organized cultures.
Worked on Cards Against iGEM InDesign. Printed and cut out our first deck for testing.

Flow notes: The first plate for time 0 contains the concentrations of doxycycline so we saw a bimodal RFP response. An explanation for this can be that the addition of doxycline had driven expression of mfalpha -> pAGA+mcherry before the cyclohexamide fixed the cells.

In the 2ml culture plate, we noticed what seems to look like debri or contamination on the bottom of the wells from rows A,B,C. We tried to make the time point plates by pipetting everything singly.
After taking a look at the 0 time point plate through the flow, we can see that the size of molecules running through are not yeast but bacterial contamination. We need to totally redo this experiment again because this contamination gives us inaccurate data.
Yesterday, the 0 time point plate was not run all the way (only 10ul was run and there were not enough events). Derrick saved the plate and I will run 100uls of each of those wells. The wells are G,H (1-5), and A,B,C,D (7-11).
2pm -> 4pm Practiced presenting poster with the group and Anusuya.

Colony PCR (refer to 6/16/14)
Gel result of Yeast Colony PCR:
MON 19 MAY 2014
Cleaned up lab. Read lots of literature.
TUE 20 MAY 2014
Looking for alpha-factor responsive promoters. Results can be found in "iGEM 2014/Parts and Plasmids/Mating Responsive Promoters/"
WED 21 MAY 2014
Continuing search for more alpha-factor responsive promoters to add to the 16 that we have found so far.
Also, designing primers for the promoters that we have found so far. For primer design, see "iGEM 2014/Protocols/cloning_DH5aT.docx"
MON 02 JUN 2014
I. Calculated Ligation concentrations found in 140602 Ligation Calculation.xlsx and performed ligation reactions.
II. Also re-PCR'd promoters that did not work before.
Please see paper notebook page 3 for gel map. Gel image: 
TUE 03 JUN 2014
I. Re-PCR'd promoters that we did not do yesterday. See gel photos:
Also gel extracted.
II. Selected colonies and inoculated cultures.
WED 04 JUN 2014
I. Digest PCR reactions and PCR cleanup. Completed. Concentration of Promoter 6 is pretty bad compared to others.
II. Inoculated single colony plates.
THURS 05 JUN 2014
I. Eric and Derrick are retrying digestion of backbone for the third time after two failed attempts. Will try ligation and transformation into e. coli today.
II. Need to miniprep plates with single colonies.
III. Linearize DNA for Yeast Transformation
Linearized PRM1, SAG1, YDR124W. See concentrations here:
FRI 06 JUN 2014
I. Designed Gibson Primers and produced Promoter + rtTA ApE files.
II. Performed gel extraction of re-digested backbone.
See gel photo below: 
.
See how the band is at the right place now at around 8kb, but that there isn't really a smaller band. Possible that the smaller band ran off the gel.
Overall: Found that most of the promoters worked out in the end with cloning. Ready for yeast transformation and integration into yeast genome. Now trying to figure out next steps.
MON 09 JUN 2014
I. iGEM Bootcamp started.
II. Minipreps of Transformations from attempt 2. Vacuum manifold does not clear PE Buffer as well as centrifuges. May have ended with more than 50microliters of product. Nanodrop showed that our concentrations are okay still. We are now sending out these samples for sequencing.
TUE 10 JUN 2014
I. iGEM Bootcamp.
II. Dual Digest of miniprepped backbones to remove GFP from built vectors → will digest overnight.
III. Worked on iGEM website.
IV. Sequencing came back and found that all miniprepped vectors turned out well → moving forward with yeast transformation and Dual digest for rtTA incorporation as seen in II.

THUR 19 JUN 2014
I. Dilute inoculated cultures. (2 hours)
Flow Cytometer Preparation
Day Before: start overnight cultures of your strains to be tested in SD complete media (NOT YPD, since it has fluorescence background and is problematic for FACS testing)
Day Of: 1. Dilute overnight cultures to final ~OD 0.05-0.1 in the 96 well shaker plate (the saturated overnight cultures should be ~OD 7, so this is approximately a 1:100 dilution. Also, where are the plates? If you don't know, ask and make a note.). Again, use SD complete media and the total volume of each well should be 1 mL. Make a plate map!
Allow cells to enter growth stage by putting on plate shaker for 3 hours at 1000 rpm, 30 degrees C.
Induce with alpha factor. The stock alpha factor in the freezer is 3 mM, and we used it at final concentrations of 0, 1 nM, 10 nM, 100 nM, and 1 uM. **Please include your concentrations for making the dilutions we used to pipette so that you can quickly and easily refer to this for next time!** Alpha factor cannot be refrozen, so throw away stocks after use.
Allow induction to proceed on plate shaker for 90 min to 2 hours, no longer.
Transfer 250 uL of each culture to the 96 well flow cytometry V-bottom plate using the multichannel pipette. Add 4µl of cyclohexamide for every 100µl of cells (10µl total) to kill cells and stop protein production.
Run on flow cytometer. Things you should note:
Check waste, turn machine on, check sheathing fluid.
Open FACS diva. Use iGEM account.Make new plate or new experiment.
Make sure settings for each well is accurate. Ensure that pick up volume is not more than volume in each well, that the mixing volume is not more than volume in each well.
Make sure laser settings, voltage settings are correct. (View>inspector)
FSC: 250 SSD: 280 FITC: 550 B: 650
Click blue button to tag selected wells as wells with samples to test.
Flow rate: 1µL/sec Sample Volume: 200µL Mixing Volume: 100µL Mixing speed: 180µL/sec
Always run wells, not run plate.
FIRST what things you need to check on the machine before running!, how to open the iGEM account and create a new FACS experiment, voltage settings (and tips on how to set an appropriate voltage setting), how to select wells and alter the volume of sample, flow speed, mixing volume, etc, how to run the plate/wells, how to export data, and anything else you might need)
- Analyze data. Notes on that from what you learned in FlowJo and MatLab today.
II. Expose to alpha factor (~90 minutes) (0, 10nM, 1µM, 10µM, 100µM)
Correction 24 JUNE 2014: (0, 1nM, 10nM, 100nM, 1µM)
Flow Cytometer 1-4pm.
How to use flow cytometer: 1. Check the sheathing fluid levels! 2. Press run 3. On computer, use flowjo. 4. Check voltages! (in notebook) 5. Select wells 6. run! 7. Make sure you see a good number of events.

WED 25 JUN 2014
I. Dilution of CB008 and CB008DB for yeast transformation of pTETGFP today @ ~1pm. Need to linearize pTETGFP for transformation later today.
Given two vectors: hy86E3(pTETGFP LEU2) pTS97(pAGA1GFP URA3)
- linearization @ 37°C started at 11:57am → 12:57pm
- No need to PCR cleanup
- Straight to transformation.
Yeast Transformation Protocol
T-(1 day) Grow yeast strains in 5-10ml YPD overnight at 30°C
T-(2–4hours) Dilute cultures ~1:20 in YPD. Grow for 2-4 hours @ 30°C to OD_600 = 0.4-0.6. Make sure to inoculate 2.5ml per transformation reaction.
T-(20 minutes) Boil salmon sperm DNA for 10 minutes and cool on ice for 10 minutes. (This can be done in the thermocycler with the ssDNA Heat-Freeze protocol) Thaw DMSO! Pellet cells (3000rpm 2-5min). Discard supernatant. Wash with 1:1 culture volume of LOATE(0.1M LiOAc in TE) or water. Pellet cells (3000rpm 2-5min). Discard supernatant. Resuspend pellet in 100µl per reaction (aka per 2.5mL of culture volume) Aliquot 100µl into each transformation reaction tube. To each tube of 100µL yeast, add:
- 10µL of ssDNA
- 8µL of target DNA(Hyun's standard amount after linearization)
- 480µL of 50% PEG 3350
- 60µL TE(10XTE)
- 60µL of LOA(1M LiOAc)
- 75µL of DMSO
Vortex! Incubate at 42°C for 30 minutes.
T+(30 minutes) Pellet (6000rpm for 2 minutes). Use pipette to remove media! Resuspend in 500µL YPD (or selective media) Pellet (6000rpm for 2 minutes). Discard media. Resuspend in residual ~50µL of YPD. Plate on selective media. Incubate for 1-3 days at 30°C.
T+(1-3 days) Pick colonies, colony PCR, or continue with experiment in some other way.

Sick today :/ Tummy hurts
See below for repeat of AFRP GFP measurements in biological replicates.
Some questions that we still need to answer:
- Why yeast instead of bacteria? Other studies have made similar circuits in bacteria before (see "Building Biological Memory by Linking Positive Feedback Loops" by Dong-Eun Chang et al.) The argument that yeast are slightly more representative of eukaryotic cells here seems far-fetched as we are not really looking at anything endogenous to yeast. Not that I think we should drop everything and start working in bacteria. We should have a solid response to this though.

- [ ] Functions
- [ ] Develop function to model pTEFrtTA -> pTETGFP/pTET_mFα.
- [ ] Need to understand how [Doxycycline] alters [α]. Does [GFP] correlate directly with [α]?

- [ ] Functions
Conclusions from today: To understand Alpha Factor Secretion, need to understand how [Doxy] -> pTEF1rtTA -> pTETGFP results translate to [Doxy] -> pTEF1rtTA -> pTETmFα -> [α]. Need this circuit: ([Doxy] -> pTEF1rtTA -> pTETmFα -> [α]) + (pAGA1RFP -> [RFP]) and then use ([α] -> pAGA1GFP -> [GFP]) measurements to understand the local concentrations of Alpha Factor from each cell.
Need to construct: ([Doxy] -> pTEF1rtTA -> pTETGFP + pTETMFα -> pAGA1RFP -> [RFP])
Questions for Hyun:
- How does one find the phenomological alpha factor secretion from the data that we currently have: [Doxy] -> (pTEF1rtTA + pTETGFP) -> [GFP] and [α] -> (AFRP_GFP) -> [GFP].
- Even though there seems to be a one-to-one correlation between [GFP] and [α], leading us to an understanding of local [α], what does that say about [rtTA-Dox] -> pTET_GFP production of GFP, and eventually [α]?

Flow Cytometry
1. Start overnight cultures of our strains to be tested om SD complete media instead of YPD (YPD has fluorescence).
2. Dilute overnight cultures to OD 0.05-0.1 in the 96-well shakeplate. The plates are in a cabinet in the limlab wrapped in shiny paper. USe SD complete media and the total volume of the well should be 1mL. Make a plate map now.
3. Allow cells to enter growth phase by putting wells in plate shakers for 3 hours at 1000rpm@30 degrees.
4. Allow induction with alpha factor. The stock alpha factor is 3mM and we used 0, 1, 10, 100, 1000nM. (Stocks cannot be refrozen, discard after use)
5. Allow cells to enter growth stage by putting on plate for 90-120 minutes, no more.96
6. Transfer 20ul of each culture to the 96 well flow-cytometry v-bottom plate. Use cycloheximide to arrest cells. Cycloheximide suspends cell division.
7. Run on Flow Cytometer
1. Check liquid box for sufficient amount of liquid, if too low, scream for help.
2. Check the second tub for liquid with clear top. It should also have some liquid, don;t shake too harshly
3. Check the gasoline tank, if kinda full dump out and add some bleach to the bottom of the container.
4. You can open the iGEM 2014 path and the default settings will be default, but check it anyway to be sure.
5. For each new experiment, load 2 neg control wells and run those first as a blank.
(Voltage settings: FSC:250, SSC:280, FTC:550
Select wells by double-clicking until it is green and you can just add more. The volume can be modified, but 200ul is suggested (decrease by 50ul from our load)
Flow speed is usually kept at either 0.5ul per second or 1ul/second and can be adjusted relatively quickly. VOlume can be less than our sample volume.
Data is exported by usb, no internet is allowed.)
8. Analyze data (graphs: histogram vs FTC,FSC vs SSC) Flowjo note on page 17 and export to matlab yo.
