Innoculated Yeast colonies in 5ml of YPD
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
Parameters of This Flow Experiment
FSC: 250
SSC: 280
FITC(GFP): 550
B(RFP): 650
Flow rate: 1µL/sec
Sample Volume: 200µL

Flowjo Notes
- 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 E. Select mean, geometric mean, and count.
- Hit refresh. Addiction numerical data should be present.
- Use mean of FITC(GFP).
MatLab Notes
- Open up new script and comment the title of the experiment
- Enter the alpha factor concentrations info. (X axis). Put in log form.
- Enter the yGEM data. This will serve as y axis. (FITC means)
- Define variables
- Tyope figure info and run to show plot.
