For Cm, 35μg/mL should be enough to kill B.S. For Amp, nothing can be concluded! Wet Work
We had 2 samples of ppL82 in DH5α in LB solution (~4mL), one from the frozen glycerol tube and one from a colony picked on a plate. Normally plasmid and cells should not be kept in freezer. So, we want to extract this plasmid, check its size and then keep it in the fridge. We do that for the 2 different samples.
- Test the concentration of DNA in each tube
- Plate a single colony (from 23/07/08) on a Cm plate - Incubate at 37°C
- Incubate at 37°C
-Pick e single colony of MC1061 (from 22/07/08) and put it in 10mL of LB (to make glycerol stocks) -Incubate at 37°C
- Add 100μL of LB+1A (mix of friday) and 10mL of LB - Incubate at 37°C
- Prepare Medium A Add 81mL of SDW, 10mL of 10X Medium A base and 9mL of 10X Bacillus salts
At, t0 = 70min, log growth seems to stop.
- Storage : we want to store 7 tubes 6 tubes in the freezer (with 60μL of glycerol) 1 tube on the bench - Transformation
