Plasmid pKs::DGAT expression in E. Coli

We tried to see TG with NR died on E. Coli cells transfected with pKs::DGAT, an IPTG-inducible promoter. We tried different growth media containing more or less oleate, that should in theory increase TG synthesis.

Results : we don't see the inductible effect of IPTG. We can think that :

  • Either the fluorescence without IPTG is due to a leak of the promoter
  • Either DGAT is not induce in presence of IPTG, and the fluorescence we see is only a background.

Growth kinetics of w121 strain

Results of the previous day : we lost everything because of a crash of the computer :(.

Transduction of MG1655 with P1 stock made on w121

  • Control (1mL LB MgSO4 30mM; CaCl2 15mM)
  • 5µL Phage + 900µL LB (MgSO4 30mM; CaCl2 15mM) + 100µL MG1655 Culture ON
  • 50µL Phage + 900µL LB (MgSO4 30mM; CaCl2 15mM) + 100µL MG1655 Culture ON
  • 500µL Phage + 500µL LB (MgSO4 30mM; CaCl2 15mM) + 100µL MG1655 Culture ON

=>For the nth time, it is not working : we have only contaminants.
