<p>PCR of lacZ beta from the galactosidase biobrick from iGEM kit. This galactosidase gene does not contain the EcoRI restriction enzyme in the end of the gene. This means we do not have to do mutagenesis to take away the restriction site. I use Q5 protocol and setup. Used primers: LaczBeta forward and LacZBeta reverse – Stop and Non-Stop. Used both galatosidace biobricks found in the kit as template. For the part 9E kit plate 2 (galactosidase w. RBS) I got clear bond for both parts.

PCR amplification of the cleaned DNA with and without stop codon.
Week 25
Tuesday
William
PCR clean-up using Machery-Nagel PCR clean-up kit on DNA with and without stop codon.
We did step 1 of making E. coli TOP10 cells competent (incubation of cells from freeze stock in LB medium with streptomycin.
We analyzed the DNA concentration using NanoDrop:
- LacZ-beta with stop codon: 230 ng/µl
- LacZ-beta without stop codon: 300 ng/µl
Wednesday
William, Håkon, Sumaya
Finished Jack's protocol for making competent cells.
Attempted to transform bacteria with these parts:
- LacZ-alpha 22D (plate 2)
- 10X His-tag 5P (plate 3)
- pBad strong promoter 14A (plate 3)
- T1 terminator 1D (plate 1)
- Double terminator 3D (plate 1)
Parts were resuspended in accordance to iGEM protocol and for the transformation we used Jack's protocol.
Plates for E. coli growth were made and the transformation products were plated.
Thursday
William, Håkon, Sumaya
Growth of 10X his-tag and double terminator transformed bacteria observed. Overnight (O/N) cultures were made of these.
LacZ-alpha, pBad and T1 were attempted transformed again.
New batch of LB-plates were made with chloramphenicol.
Friday
William, Håkon, Sumaya
Restriction cutting of LacZ-beta STOP cleaned PCR product, LacZ-beta NONSTOP cleaned PCR-product and pSB1C3 were attempted using restriction enzymes XbaI and PstI. Incubation in accordance with iGEM restriction digest protocol. The tube with pSB1C3 was not mixed with water before pipetting.
The concentration of the digested products were measured in NanoDrop:
- LacZ-beta stop: 14.4 ng/µl
- LacZ-beta non stop: 23.3 ng/µl
- pSB1C3: 26.5 ng/µl
Ligation was attempted on the digestions using T4 DNA ligase and following the iGEM ligation protocol.
Freeze stocks of the O/N cultures of 10X His-tag and double terminator were made.
Minipreps using Promega Wizard Plus SV miniprep kit was attempted on saturated 10X his-tag and double terminator cultures.
Cultures observed on pBad, LacZ-alpha and T1-terminator plates. O/N cultures made during the weekend.
Week 26
Monday
Sumaya
The pBad, LacZ-alpha and T1-terminator O/N cultures were miniprepped.
Agarose gel electrophoresis showed bands in all lanes (picture 12).
Freeze stocks made of pBad, LacZ-alpha and T1-terminator transformed bacteria.
The ligated products from the 20th were used in a transformation attempt.
Tuesday
William, Sumaya
No colonies seen on the LacZ-beta stop and non stop plates.
Preformed new digestion of parts using pSB1C3 solved in 30 μl dH2O and XbaI and PstI.
Wednesday
Sumaya
The digestions were cleaned up using the Machery-Nagel PCR clean-up kit.
Ligation was done following the iGEM ligation protocol, but running two parallells – one with and one without heat shock.
Thursday
William, Håkon
Made O/N culture of T1 terminator from freeze stock in order to obtain pSB1C3 plasmids in case the pSB1C3 from the tube in the kit is defective.
We tested the restriction digest protocol by using a part from the kit we don't need (1A). Due to issues with the agarose gel we started over using another part (1K) that we left it in 37C for 4 hours and then on 4C overnight.
Friday
William, Sumaya
Miniprep of the T1 terminator O/N culture. 3 MP's made in parallel with NanoDrop DNA concentrations:
- T1-1: 15.6 ng/µl
- T1-2: 16.7 ng/µl
- T1-3: 16.2 ng/µl
The T1-1 was digested using XbaI and PstI following the iGEM digestion protocol.
The product was run on a gel and we cut out the pSB1C3 part using a scalpel and stored it in a eppendorf tube in the fridge.
Saturday
Håkon
Made freeze stock of Lac-Z beta stop transformed Top 10 cells.
PCR was preformed on LacZ-beta with stop and non stop reverse primers using Q5 polymerase.

Tuesday
Håkon
Testing Lac Z beta stop on gel, and transformation of Lac Z beta stop into competent cells.
Sumaya
Transformation of E.coli with LacZ-beta stop (without EcoRI site) was attempted and transformation of flourecent protiens was attempted.
These flourecent protiens were found in the iGEM kit:

Digestion of Lac Z beta-stop with only the EcoR1 enzyme was also attempted.
Wednesday
Vilde
Made N-Histag from primers. Used the program called “gradient” in the PCR machine. Started at 95 deegree and went slovly down to 55 degrees. Found out that this was the wrong program to use.
Håkon
Blunt end ligation of pure linear pSB1C3 to control the ligation reaction.
Sumaya
Ran PCR using the TaKaRA PCR setup and ran agorose gel to check if the transformations had work.
These were tested:

All of these had bands.
Thursday
William, Håkon
O/N cultures were made of the colonies of transformed pSB1C3/LacZ-beta non-stop.
PCR was run with VR2 and VF primers for confirmation.
Vilde
Made new N-term His-tag primers. Used Waterbath this time. Put the waterbath at 95 degrees, mixed the Forward and reverse oligoes for the N-his term and put them in the waterbath. Let the temperature slowly go down to about 50 degrees.
Vilde
Made a big O/N culture of the pSB1C3 C-term His to isolate the plasmid backbone tomorrow. Made a 50ml O/N culture with chloramphenicole. 50ul Chloranphenicole in 50ml LB medium.
Izadora
A PCR on BL21 and AB2848 strains of bacteria was repeated to retrieve LacZ-beta gene. The LacZ-beta Non-Stop and LacZ-alpha Non-Stop primers were used.
The fragment-size in the agarose gel (0.7%) was like expected.
A miniprep was performed on O/N cultures with colorful parts from the Kit (19E, 11N, 2I and 2K) using Promega Wizard Plus SV miniprep kit.
Friday
William, Håkon
3A assembly was attempted with the bricks pBad and 2I, 2K, 19E and 11N, using pSB1A3.
Vilde
Miniprepped lacZ-beta Non-stop pSB1c3 (Wizard Miniprep). Final Concentration of 95 ng/ul.
Vilde
Quickchange mutagenesis of LacZ beta non stop. One of the parts we are making contains an EcoRI site. We will do a mutagenesis to get read of this site. Used 7,5ul primers and 6 min elongation. Followed the quickchange protocol and used pfu Turbo enzyme from agilent technologies.
Vilde
A3 assembly of lacZ Alpha Stop and LacZ beta NS into pBAd.
Saturday
Vilde
No colonies after the mutagenesis or A3 assembly. Troubleshooted it.
Week 28
Monday
William, Håkon
Batch of LB agar plates w/Ampicillin was made.
Vilde
Made primers for Autotransporters.
Vilde
Ordered primers for Autotransporters, Signaling peptide, Primers to amplify linearized plasmid backbone and VR, VF2 primers.
The primes contains the standard prefix and suffix. Non of these genes contains any of the restriction sites for the restriction enzymes in the iGEM assembly protocol.
- Invefull Long
- Invfull Short
- Ehaj1 – Short
- Ehaj2 – long
- Signalling peptide
Vilde
Assembled lacZ beta Stop and NS (Cleaned up PCR products) into pSB1C3 plasmid.
Cut both plasmid and parts with EcoRI and PstI. Ligated for 1h at RT. Transformed 2 ul.
Sumaya
Made 2 overnight cultures (O/N) from two different colonies of pBad-beta non-stop, His 1- α-stop, His 1- α-stop, pBad-2K, pBad-2I, pBad-19E, and pBad-11N
Also made the agrose gel for the gel electrophorese.
Izadora
A PCR on colonies from O/N cultures following the TaKaRa® enzyme protocol was performed, but increasing the extension time to 4:20min (when using iGEM’s primers VF and VR2).
Samples below:
- pBAD - LacZ-beta Non Stop
- HisTag 1 - LacZ-alpha Stop
- HisTag 2 (in a different concentration) - LacZ-alpha Stop
- pBAD - 2K
- pBAD - 2I
- pBAD - 19E
- pBAD - 11N
An A3 assembly in the pSB1A3 plasmid following iGEM protocol was done, but the ligation taking place at 16°C O/N as shown below:
- Part A: pBAD
Part B: LacZ-alpha Non Stop
Tuesday
William, Håkon
The results of the 3A assembly was poor, with either no growth at all or carpet growth.
The O/N cultures from the day before was made without using antibiotics, so the cultures was transferred to fresh medium with antibiotics to try to select for the right bacteria.
2I, 11N, 2K and 19E was plated on LB agar with 0.1% arabinose.
New batch of LB agar was made, using LB broth powder.
Vilde
No growth observed from the assembly into pSB1C3. We think there may be something wrong with the linearized plasmid. We will try to amplify the plasmid by PCR from another part and use that one in the assembly work.
Vilde
- Found out that the iGEM scar contains a Stop codon
- Found tRNA amber Stop – part in the kit
- Found a constitutive promoter
- Found plasmid (from jack) with another origin of replication
Izadora
An analytical gel electrophoresis was performed in a 0.7% agarose gel with samples from last PCR and O/N ligated products from A3 assembly. The fragment-sizes in the gel were like expected just for BAD -11N and HisTag 1 - LacZ-alpha Stop.
The gel electrophoresis was repeated with increased volume of sample (20μL) and all fragments presented the expected size.
A Transformation with the O/N ligated product from A3 assembly was attempted using the agar plates with the correct antibiotic at the right working concentration.
Wednesday
Vilde
- Transformed Amber stop – tRNA and promoter
- Amber stop tRNA - Part: K228001, 14E kit plate 3
- constitutive promoter – Part J23119, 17O kit plate 3
Sumaya
Miniprepped pBad Lac Z beta non-stop as the others had failed.
Attempted a mutagenisis of the pBad-Lac Z beta non-stop.
Izadora
There was no growing in the transformation.
Thursday
Vilde
Got colonies from transformation of the amber stop tRNA and promoter. Tested the colonies on PCR with the VF and VR2 primers. Made O/N cultures in LB chloramphenicole medium.
Izadora
The transformation worked for samples 17O, 14E, 13L, but not in pBAD - LacZ-alpha Non Stop.
A PCR clean-up of PCR products of LacZ-beta and -alpha Non Stop from both AB2848 and BL21 strains was done, following Machery-Nagel PCR clean-up kit’s protocol.
The Concentrations were measured in NanoDrop (NanoDrop 1000 3.8.1) for each cleaned sample:
- LacZ-beta Non Stop (AB2848): 109.8 ng/µl
- LacZ-beta Non Stop (BL21): 36.4 ng/µl
- LacZ-alpha Non Stop (AB2848): 74.8 ng/µl
- LacZ-alpha Non Stop (BL21): 91.9 ng/µl
After that, an A3 assembly (as in 07.07.14) was attempted with PCR cleaned-digested products, digested pBAD and pSB1A3 following iGEM’s protocol with O/N ligation.
Friday
William, Sumaya, Izadora
O/N cultures was miniprepped and freeze stocks were made of:
- pBad + 19E in pSB1A3
- pBad + 2K in pSB1A3
- pBad + 2I in pSB1A3
- pBad + 11N in pSB1a3
- 13L in pSB1A2
- His alpha stop in psB1A3
- 19E in pSB1C3
All in TOP10 E.coli cells.
New transformation was set up using the following ligation products:
- LacZ alpha NS (from AB strain) + pBAD + pSB1A3
- LacZ alpha NS (from BL strain) + pBAD + pSB1A3
- LacZ beta NS (from AB strain) + pBAD + pSB1A3
- LacZ alpha NS (from BL strain) + pBAD + pSB1A3
The NCM17 E.coli strain was received from Yale E.coli Repository, plated and overnight cultured.
Vilde
Miniprepped and made freeze stock of Amber tRNA and constitutive promoter.
Izadora
A frozen stock was prepared with O/N cultures and Glycerol 60% (1/1).
There were no colonies from transformation with pBAD-LacZ-beta Non Stop (Mutated with EcoR1).
A transformation with O/N ligated products and with part 17O (constitutive promoter) was attempted with 2μL of ligated products and 30μL of TOP 10 competent cells.
50mL of SOC medium was prepared with: 10mM of MgSO4 and 2% of Glucose. The volume was completed to 50mL with LB medium and the final medium was sterilized with syringe filter (0,2μm).
The SOC medium was tested for contamination in test tubes by O/N incubation at 37°C and 180rpm.
The strain NCM17 without LacZ gene has arrived and was plated out in agar-kanamycin (Adgene®, working concentration = 50μg/mL) and test tubes without antibiotics by O/N incubation at 37°C and 180rpm (in the case of test tube only).
Week 29
Monday
William
Freeze stock was made of NCM17 strain.
Vilde
Tested the function of the pfu Turbo enzyme. The enzyme was forgotten at RT for 48h. I therefore tested if it was still functional by running a pcr on genomic DNA with Actin primers. I used the pfuTurbo protocol 600410. Results: No bands. The PCR was repeated with different primers and substrate but still showed no results. We concluded with that the enzyme is not functional anymore.
Izadora
One colony of NCM17 strain was picked up and incubated in a test tube by O/N incubation following the same protocol. The plate was stored at 4°C.
There were no colonies from transformation of 11.07, but for part 17O.
For sample 17O, O/N culture with chloramphenicol (Adgene®, working concentration = 25μl/mL) was prepared as before.
Tuesday
William
O/N culture of bacteria transformed with 17O was miniprepped.
Vilde
Cleanup-day in the lab! We tested all the minipreps we got in the freezer. Used Takara enzyme and general reaction mix. Tested them all on PCR and run a gel afterwords. We found out that all our plasmids contain the gene we expected.
Izadora
The gel electrophoresis was performed in agarose gel (o.7%) with digested and ligated parts.
The fragment-sizes were like as expected just for ladder and LacZ-alpha and -beta Non Stop digested products, but not for pSB1A3 and pSB1C3.
A PCR test was performed in all miniprep that we have so far using TaKaRa® enzyme and following its protocol with VF/VR2 program.
Using the Promega Wizard Plus SV miniprep kit, a miniprep was performed in O/N cultures with part 17O, storing it at -20°C. Frozen stocks of cells were prepared for O/N cultures with 60% Glycerol (1/1) and stored at -80°C.
Wednesday
William
Made 20 LB plates with kanamycin.
The miniprep of LacZ beta NS in pSB1C3 was run on a gel. The bond was the right size.
Vilde, Izadora
A3 assembly of constitutive promoter and amber stop tRNA. Followed protocol from iGEM kit. With some small changes – used only ¼ of the reaction volume.
- Part A: Constitutive promoter
- Part B: amber stop tRNA.
- Linearized plasmid: pSBA1A3
Since the RNA made from the amber stop tRNA gene will not be translated into proteins, a RBS in front of the gene is not necessary. I therefore ligated the promoter directly to the gene.
- Digestion buffer: NEB 3.1
- ligation time: 1h at RT.
- Transformed 3 ul of the ligated product.
Elina
N-His-Tag to pSB1C3
Thursday
William
The NCM17 strain was made competent (Using Jack Leo’s protocol) and put in freezer.
Vilde
No growth observed after the A3 assembly. Troubelshooting.
Vilde
New Assembly of amber stop tRNA and the constitutive promoter. Tried the assembly again, but this time with a larger reaction volume, 1/2 of the original volume. Also used the cutsmart buffer and not the NEB 3.1 buffer. I also changed and used the pSB1K3 plasmid instead of the pSB1A3 plasmid.
Vilde
Received primers for autotransporters and signaling peptide. Made stock solution and user stocks (5uM) of the primers.
Izadora
A PCR on 4 different colonies from transformation with pSB1K3 was done with TaKaRa® enzyme, following its protocol.
No fragments were observed in the agarose gel 0.7% after gel electrophoresis, but the ladder.
100mLof LB medium with kanamycin was prepared (Adgene®, working concentration = 50μg/μL) and sterilized with a syringe filter (0,2μm).
6L of LB medium and 6L of LB/agar 1% were prepared following the manufacturer’s protocol.
The 4 colonies were incubated in test tubes by O/N incubation as before.
Friday
Vilde
Growth from the A3 assembly of amber stop tRNA and constitutive promoter. Checked colonies on PCR with VR and VF2 primers and made O/N cultures of positive colonies.
Vilde, Sumaya
Minipreped and made freeze stock of Izadoras O/N cultures of LacZalpha in pSB1K3. Used wizard miniprep protocol.
Week 30
Monday
Vilde, Sumaya
A3 assembly of His-Tags into LacZ beta. Used A3 assembly protocol from iGEM.
- Part A: N-term His
Part B: B-Stop - Part A: Beta-Non Stop
Part B: C-term His - Part A: C-term his
Part B : T1 terminator
Found out that these lacZ beta parts still contains the EcoRI site. The samples will not be used. Assembly nr.3 (C-term-his to T1 terminator) will be used in future work.
Vilde, Sumaya
We found out that the promoters we have been using do not contain a RBS in front of it. We will therefore need to make new constructs with a RBS in between the promoter and the gene. I found and transformed these RBS from the kit:

Ligation with previous digested products was repeated as before and the transformation as well.
Wednesday
Vilde
No growth in the O/N culture except from the promoter-Amberstop-tRNA in the pAC-plasmid. We found out that we had used the work tetracycline antibiotic.
Vilde
PCR of lacZ beta from the galactosidase biobrick from iGEM kit. This galactosidase gene does not contain the EcoRI restriction enzyme in the end of the gene. This means we do not have to do mutagenesis to take away the restriction site. I use Q5 protocol and setup. Used primers: LaczBeta forward and LacZBeta reverse – Stop and Non-Stop. Used both galatosidace biobricks found in the kit as template. For the part 9E kit plate 2 (galactosidase w. RBS) I got clear bond for both parts. We will use these parts for future work.
Sumaya
Miniprepped pBad-RBS and promotor -amber tRNA O/Ns.

Saturday
Izadora
The DNA concentration was measured by NanoDrop (NanoDrop 1000 3.8.1) in the following samples:
- InvFull long: 40.9ng/μL
- Ehaj 1: 45.9ng/μL
- LacZ-beta Stop: 41.0ng/μL
- LacZ-beta Stop: 37.6ng/μL
- Signal peptide: 65.2ng/μL

An A3 assembly was done using RBS - pSB1C3, but after digestion the digested products were tested in a gel electrophoresis with agarose gel (0.7%).
No fragments were seen, but the ladder.
In an attempt to correct subsequent failures of A3 assembly, the iGEM’s protocol was changed and 500ng of DNA was used, instead of 250ng suggested. For that reason, the digestion was performed at 37°C for 1hour.
In addition to that, the transformation efficiency kit from iGEM was used following the protocol to check the efficiency of the competent cells being used.

Vilde
Made O/N cultures of colonies from yesterday’s 3A assembly. I got colonies on assembly: 1,4,5,6,7,9 and 13.
Vilde
3A assembly. Due to few colonies from yesterday’s assembly, I suspect something wrong with the parts we already got. I will thus make some of them again from scratch by 3A assembly. Followed iGEM’s protocol and procedure. I ligated them all in to the pSB1K3 plasmid from the kit.

- CtermHisTag - T1
- LacZ-beta pSB1C3
- pBAD - RBS
- CtermHisTag
- T1
- RBS 4G
The double of lysis buffer was used.
The DNA concentrations of the isolated plasmid DNAS were measured in NanoDrop (NanoDrop 1000 3.8.1):
- CtermHisTag - T1: 15.9ng/μL
- LacZ-beta pSB1C3: 40.1ng/μL

- CtermHisTag: 80.3ng/μL
- T1: 49.3ng/μL
- RBS 4G: 24.4ng/μL
The 280/260 value for samples 1 and 3 were too lower than 1.80, indicating presence of contaminations.
A gel electrophoresis in agarose gel (0.7%) with these plasmid DNAs was performed and the fragment-sizes were like expected, but no fragments for samples 1 and 3 were could be seen.
Another digestion was performed in RNS 4G and T1 and they were checked by gel electrophoresis in agarose gel (0.7%) before being used for ligation.
An O/N culture was prepared with pBAD in LB/chloramphenicol as previously.
Wednesday
William
The digestion of the 3A assembly protocol was done with:
N-His tag, pBad and constitutive promoter (17O) as part A’s (cut with EcoRI and SpeI). LacZ alpha stop, lacZ beta stop and RBS as part B’s (cut with PstI and XbaI). pSB1A3 and pSB1C3 as plasmids (cut with PstI, EcoRI).
Vilde
3A assembly. Tested colonies from 3A assembly from 04.08 and 05.08 by PCR. Used TaKaRa enzyme and followed 50ul setup. Used elongation 4,3 min and annealing 55degrees. The gel showed only one positive colonies. The gel showed a lot of religated plasmids (bonds of 250bp). I troubleshootet the problem and found out that I will start to de phosphorylated the plasmid to prevent relegation.
Vilde
Minipreped O/N cultures from ligation 04.08. Wanted to test them on PCR to be sure that it is nothing wrong with the way we are doing PCR to test colonies. Tested the concentration on nanodrop – all samples had a concentration between 50-80ng/ul and good 260/280 values. However all the samples had low 230/260 values that indicates that there are co-purified contaminants in the sample.
Vilde
Digested the minipreps and run gel on them. Run gel on the samples minipreped. The results showed that only Alpha-NS-Ehaj1 gave us the expected size of fragments in the gel. However for the smallest parts (RBS, T1 etc) we will not expect to see the bond from the part after digestion only the linearized plasmid. We can thus not say if these parts are correct or just re-ligated plasmids.
Vilde
Tested the one positive colony on PCR to be completely sure it is correct. Used gene specific primers (for Ehaj and LacZAlpha) combined with the iGEM VR and VF2 primers to be sure the fusion protein is in the plasmid.
Thursday
William, Håkon
Colonies from a plate with growth of LacZ-beta transformed bacteria were put in tubes, mixed with 20 µl water, heated to 96oC for 10 minutes and then centrifuged at 11.000 rpm for 10 minutes.
A PCR was set up in order to amplify the LacZ beta fragment, but there was no result on the gel.
Vilde
Run gel on PCR from yesterday. Run the gel on the PCR from 06.08. I got bonds as expected and can thus say that the part LacZalpha NS – Ehaj1 is in the plasmid.
Vilde, Håkon
I tested more of the 3A assembly colonies from 05.08 on PCR. Hopefully not all of them are re-ligated plasmids. Used TaKaRa setup (25ul). I tested 3 different colonies from CtermHis –T1 and three from C-termHis-DT. Run the PCR with Håkon.
Vilde
Negative PCR results. Found out that Håkon had used a too short elongation time for my samples to be amplified. Have to do a new PCR on the colonies.
Vilde
Dephosphorylated pSB1C3. Used the pSB1CR Izadora cut (with EcoRI and PstI)and purified from gel yesterday. Used 17ul of purified pSB1C3, 2ul of 10X buffer and 1ul of phosphatase. Let the reaction in 37 degrees for 15 minutes and heat inactivated the enzymes by leaving the sample at 75degrees for 5 minutes. Stored the sample at -20 degrees.

Vilde
Made O/N culture of LacZ-gene from iGEM kit that I will use to make constructs.
Wednesday
Vilde
Minipreped the bacterial O/N culture containing LacZ-Gene from iGEM kit.
Vilde
It seems like we have a problem with the digestion of our constructs and or plasmid since we get religated plasmids. I tested all the restriction enzymes stepwise with the corresponding buffer. I used the protocol and setup supplied with the enzyme. I used the EcoRI buffer for EcoRI enzyme, NEB3.1 for SpeI and Cutsmart for XbaI and PstI. I cut a known plasmid from the iGEM kit. Analysis of cut constructs in a gel shows that all restriction enzymes are functional, but has to be done with correct buffer.
I cut the linear plasmid backbone in a stepwise matter
Vilde
Cut pSB1C3. Cut one sample of the plasmid backbone with EcoRI and one with PstI. Used correct buffer for both enzymes. I cut the samples at 37 degrees for 1 hour.
Vilde
PCR cleaned up of the cur plasmid backbone samples eluted the samples in 20ul dH2O.
Vilde
Cut the plasmids backbone with the other enzyme using supplied protocol and buffer. Stored the stepwise cut plasmid backbone in -20 freezer for usage in ligation later.
Friday
Vilde
PCR to amplify new constructs from plasmid DNA. Used gene specific primers and template corresponding to the construct I will make. Used the whole LacZ gene as template for LacZbeta NS, lacZBeta Stop, LazC alpha NS. Used isolated plasmids containing the autotransporter gene to amplify the autotransporter and signaling peptide. I used Q5 polymerase and a 50ul reaction volume. The samples were cut and ligated into already cut plasmid (10.09) and transformed into Top10 cells.
Vilde
Sent samples to sequencing. Ehaj1 pSB1c3 with VF2 and VR primers, pBAd-RBS with VR primers. Used 5ul DNA (80ng/ul) and 5ul 5mM primers

Checked colonies on PCR (from 19.09). Used TaKaRa PCR and VF2, VR primers. The colonies did not give bands as expected.
Vilde
Checked Sequencing results. It seems like our constructs do not contain the whole suffix. I made new reverse primers to test if this lack of the whole suffix may be due to wrong primers.
Week 39
Thursday
Vilde
Got the new primers and set up PCR to make new constructs. Used Q5 and gene specific primers. Made: LacZBeta NS, LacZ Beta Stop, LacZ alpha Ns, Ehaj1, Ehaj2 and signaling peptide. All were positive except lacZ alpha non stop.
Vilde
Stepwise digestion of the PCR products and pSB1C3. Cut the constructs and the plasmid backbone stepwise using the correct buffer to each enzyme and a PCR cleanup in between.
Vilde
Dephosphorylated the plasmid backbone to prevent relegation
Vilde
Ligated the cut constructs into the cut and dephosphorylated plasmid backbone. Used T4 ligase and followed the protocol supplied with the enzyme. Transformed only LacZ beta Non stop due to lack of competent cells.
Friday
Vilde
Growth was observed for the transformed LacZ Beta Non-Stop from 25.09.
Vilde
Showed Håkon And William what I have been doing so they can continue making the constructs after I move to Germany.
Week 40
Monday
Håkon
O/N of top 10 e.coli with pASK-IBA3 plasmid were prepared.
Tuesday
Håkon
PCR was preformed on Lac-Z alpha stop using VF2 and VR primers.
Miniprep of O/N culture with pASK-IBA3 was preformed.
Lac-Z beta and Lac-Z alpha were measured in nanodrop.
Wednesday
Håkon
Sequencial cutting with EcorI and PstI was preformed followed by alkaline phophatase treatment.
Ligation reaction was put on incubation for 1 hour and transformation preformed directly after.
Thursday
Håkon
New transformation was preformed using our standard protocol and competent NCM17 E.coli cell with deleted Lac operon.
Saturday
Håkon
Colonies were selected and O/N were made.
Sunday
Håkon
Miniprep was preformed on all O/N cultures. No gowth in the O/N cultures!
Week 41
Wednesday
Håkon
Sequencial digestion with EcorI and PstI using the correct buffers and PCR- clean-up between the two digestions. Digestions tested on gel, but results was negative.
