Survival-Test of one 14_3C clone( SG9-P10) and one Tev-clone (SG13-T6)

Investigators: Paul, Stefan, Sascha

Aim: Test whether TorA-detection device functions

  • SG13-T6 contains two silent mutations and one single amino-acid exchange (N-->D)
  • SG9-P10 contains different mutations:...

Plates:

30x, 15x for each clone

  • 2x Cm (25 µg/ml)
  • 2x Cm + 1mM IPTG
  • 2x Cm + 1mM Ara
  • 2x Cm + Amp (50 µg/ml)
  • 2x Cm + Amp (200 µg/ml)
  • 2x Cm + 1mM Ara + Amp (50 µg/ml)
  • 2x Cm + 1mM Ara + Amp (100 µg/ml)
  • 2x Cm + 1mM Ara + Amp (200 µg/ml)
  • 2x Cm + 1mM Ara + Amp (400 µg/ml)
  • 2x Cm + 1mM Ara + Amp (800 µg/ml)
  • 2x Cm + 1mM Ara + 1mM IPTG + Amp (50 µg/ml)

  • 2x Cm + 1mM Ara + 1mM IPTG + Amp (400 µg/ml)
  • 2x Cm + 1mM Ara + 1mM IPTG + Amp (800 µg/ml)

Method:

  • cells from glycerolstocks (-80°C) were inoculated in 5 ml LB-Medium (Cm = 25µg/ml). Then diluted and incubated until OD=0.002
  • 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
