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 the 4 tubes we added rapalog in order 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.
