Lab work

A - Aerobic/Anaerobic regulation system / B - PCB sensor system

Objective : obtaining FNR and BphR2 proteins

1 - Electrophoresis of Colony PCR of FNR, RBS-FNR and RBS-BphR2

]]
  • Well 1 : 6µL DNA Ladder
  • Well 2 to 17 : 5µL of FNR+1µl of 6X loading dye
  • Well 18 to 26 : 5µL of RBS-BphR2+1µl of 6X loading dye
  • Well 27 : 6µL DNA Ladder
  • Well 28 to 41 : 5µL of RBS-FNR+1µl of 6X loading dye
  • Well 42 to 49 : 5µL of RBS-BphR2+1µl of 6X loading dye
  • WEll 50 : 6µL DNA Ladder
  • Gel : 1%

Expect sizes :

  • FNR : 1096 bp
  • RBS-FNR : 1014 bp
  • RBS-BphR2 : 1469 bp

We obtain fragment at right size for FNR and RBS-FNR. The Gisbon assembly was good.
