-
- Prepare medium A with tryptophan, and medium B
 
-
 
-
- add 5mL of medium A in 3 different tubes, inoculate each tube with colonies (1A1, IA751 ans IA771)
 
-
 
-
- Check OD every 20min
 
-
 
-
- Incubate 90min
 
-
 
-
- Add 0.45mL of medium B and 0.05mL of culture in Ependorf tubes
 
-
 
-
- Incubate 90min
 
-
 
-
- Transform : add 1μg of DNA (some with ECE112, some with ECE166) (so you need to nanodrop samples before!)

- A few glycerol tubes to stock cells : add 2/7 glycerol to cell tubes

- Transformation from glycerol stock from 30/07/2008

-
- Spin glycerol stocks, pipette out glycerol
 
-
 
-
- Add 0.5mL of medium B, incubate for 1 hour

-
- Add 10μL of ECE112 (640ng)

==New stocks==
 
-
 
-
- Do glycerol stock of I746001 and I746101 (no sterile glycerol)
 
-
 
-
- Put IA751, IA771 in 10mL LB
 
-
 
-
- Put ECE 176 in 10mL LB + antibiotic
 
-
 
-
- Reinoculate the tube of LB from yesterday with ECE166 plate
 
-
 
-
- ECE176 replated onto Amp100 + Cm5
