Lab work

A - Aerobic/Anaerobic regulation system

Objective : characterize Bba_K1155000, Bba_K1155004, Bba_K1155005, Bba_K1155006

1 - Results of liquid culture of Pfnr-RBS-Amil CP-Term in PSB1C3 in aerobic and anaerobic conditions

XiaoJing

IT WORKS !!!

In anaerobic conditions, thank to promotor Pfnr, RBS-Amil CP-Term gene is activated and we can see a violet coloration of bacterias.

In aerobic conditions, promotor Pfnr is inactivated and RBS-Amil CP-Term too, the dectetion gene isn't activated and we can't see any coloration of bacterias.

2 - Results of culture of Pfnr-RBS-Amil CP-Term in PSB1C3, NirB with RBS-LacZ-Term in PSB1C3 in aerobic and anaerobic conditions

XiaoJing

Purification of 08/22/13 didn't work. We have blue colonies for Pfnr with RBS-Amil CP-Term in PSB1C3 in aerobic and anaerobic conditions. We also have blue colonies for NirB with RBS-LacZ-Term in PSB1C3 in anaerobic conditions.

3 - Ligation of Pfnr with RBS-LacZ-Term in PSB1C3

XiaoJing

Used quantities :

  • Pfnr : 8µL
  • RBS-LacZ-Term in PSB1C3 : 3µL
  • Buffer ligation : 2µL
  • Ligase : 1µL
  • H2O : 6µL

4 - Transformation of ligation of Pfnr with RBS-LacZ-Term in PSB1C3 in DH5α

XiaoJing

Protocol : Bacterial transformation

We incubate it at 37°C with Xgal in aerobic conditions.

((((((((((((((====Objective : obtaining Pfnr, NarK, NarG or NirB and RBS-LacZ-Term or RBS-AmilCP-Term in PSB3K3====

1 - Ligation of Pfnr with RBS-LacZ-Term in PSB3K3 and NarK with RBS-LacZ-Term in PSB3K3

XiaoJing

Used quantities :

  • Pfnr, NarK : 3µL
  • RBS-LacZ-Term : 3µL
  • PSB3K3 : 5µL
  • Buffer ligase : 2µL
  • Ligase : 1µL
  • H2O : 6µL

2 - Transformation of ligation of Pfnr with RBS-LacZ-Term in PSB3K3 and NarK with RBS-LacZ-Term in PSB3K3 in DH5α

XiaoJing

Protocol : Bacterial transformation

We incubate it at 37°C with Xgal in anaerobic conditions for NarK with RBS-LacZ-Term in PSB3K3. We incubate it at 37°C with Xgal in aerobic conditions for NarK with Pfnr-LacZ-Term in PSB3K3.

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 of 08/26/13 was good.
