- 100µl of cells with OD=0.002 were plated on prepared plates
Results:
Survival screening have to be repeated, because there is no way to compare numbers of clones on plates (dual induction of protease via AraC and ssTorA_CS_blaFL construct via IPTG) with number of clones on the right controll plates (singel induction with IPTG to check the export via TAT-pathway of beta lactamase.
No resistance against ampicillin without induction with IPTG. Dual-induction with arabinose and IPTG does not lead to a dramatical reduced number of clones.
Further Tasks:
- Repeat the survival test with singel induction via IPTG as comparison for the cell death based on reduced export of beta lactamase into the periplasm of E.coli
- repeat survival test at 37 °C for both protease to check influence of creation of inclusion body of TEV protease at 37°C and influence of export capacity of beta lactamase via TAT-pathway
