No clone was observed on the control plate from 18/10 Clones have grown on the other plates.

Transformations were done from the Petri dish containing the preparation diluted 10 times with :

50 mL LB (CM 15μg/L+Amp 50μg/L) 500μL of cell preparation at DO=2,2

This preparation was divided in 4 tubes of 4ml and a falcon of 32 ml.

In 1 pool of 4 tubes we added rapalog in order to test the fluorescence : tube1 : control without rapalog tube 2 : 5 nM of rapalog tube 3 : 50 nM of rapalog tube4 : 500 nM of rrapalog

After 5 hours of culture, cytometry didn't show any fluorescence.


For the falcon of the remaining preparation (32ml) :

  • Centrifuge
  • Discard the supernatant
  • Resuspend the pellet in 15 ml of 100mM Tris (pH= 7,4), 100mM NaCl, 10 % glycerol
  • Discardthe supernatant
  • Resuspend in 800 μL of TNG buffer and 20μL of PMSI
  • Divide the preparation in 8 eppendorf (100μL)
  • For one eppendorf : add « cap of glass bead, acid washed) 150-212μm sigma »
  • 30 min on vortex
  • Add 100μL of buffer in each tube
  • centrifuge
  • Add Rapalog at 150nM in each tube except for one control
  • Incubate 30 min
