There was no clone on the control plate from 18/10. Clones have grown on the other plates.
Transformations were done from the plates 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 tube of 32 ml.
In the 4 tubes, we added rapalog to test the fluorescence:
After 5 hours of culture, cytometry didn't show any fluorescence.
For the falcon of the remaining preparation (32ml):
Read on a plate at 488 nm excitation.
