We obtain fragment at the right size for PSB1C3. We will purify it. We used an electronic eppendorf gun too fast, some product get up and fill from well 3 to well 4 and 5.

Lab work

A - Aerobic/Anaerobic regulation system

Objective : characterize Bba_K1155000 and Bba_K1155004

1 - Colony PCR of ligation Pfnr or NirB with RBS-LacZ-Term or RBS-Amil CP-Term in PSB1C3

XiaoJing

Transformation of 08/26/13 works. We will do a PCR Colony.

Pick up single clone and dip in 10µL H2O into each tube.

Used quantities :

  • DNA : 2µL
  • Mix  : (it was divided in 6 tubes for each promotor with 23µL of mix in each tube)
    • Oligo 44 : 17.5µL
    • Oligo 43 : 17.5µL
    • Buffer Dream Taq : 87.5µL
    • dNTP : 17.5µL
    • Dream Taq : 7µL
    • H2O : 591µL

PCR Program :

2 - Gel electrophoresis of the colony PCR products : Pfnr or NirB with RBS-LacZ-Term or RBS-Amil CP-Term in PSB1C3

XiaoJing

[[]]
  • Well 1 : 6µL DNA ladder
  • Well 2 to 7 : 10µL of NirB with RBS-LacZ-Term in PSB1C3+2µL of 6X loading dye
  • Well 8 to 13 : 10µL of NirB with RBS-Amil CP-Term in PSB1C3+2µL of 6X loading dye
  • Well 14 to 19 : 10µL of Pfnr with RBS-LacZ-Term in PSB1C3+2µL of 6X loading dye
  • Well 20 to 25 : 10µL of Pfnr with RBS-Amil CP-Term in PSB1C3+2µL of 6X loading dye
  • Gel : 1%

Expected size : 3583bp ????

  • NirB with RBS-LacZ-Term in PSB1C3 :
  • NirB with RBS-Amil CP-Term in PSB1C3 :
  • Pfnr with RBS-LacZ-Term in PSB1C3 :
  • Pfnr with RBS-Amil CP-Term in PSB1C3 :

We obtain fragments at the right size for NirB with RBS-Amil CP-Term in PSB1C3 in well 12, Pfnr with RBS-LacZ-Term in PSB1C3 in well 14, 15, 18 and 19 and Pfnr with RBS-Amil CP-Term in PSB1C3 in well 20, 22 and 25. Nevertheless, electrophoresis shows that these colonies weren't pure. We will purify them by streaking.

3 - Streak of NirB with RBS-Amil CP-Term in PSB1C3, Pfnr with RBS-LacZ-Term in PSB1C3 and Pfnr with RBS-Amil CP-Term in PSB1C3 to purify them

XiaoJing


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

Objective : obtaining FNR, BphR2 proteins

1 - Electrophoresis of RBS-BphR2 Part I, BphR2 Part II, FNR Part I , FNR Part II, RBS-FNR Part I and PSB1C3

XiaoJing

Gibson tranformation of the 08/27/13 didn't work. So we did an electrophoresis to check sizes and concentrations of Gibson parts.

[[]]
  • Well 1 : 6µL DNA ladder
  • Well 2 : 5µL of PSB1C3+1µL of 6X loading dye
  • Well 3 : 5µL of RBS-BphR2 Part I+1µL of 6X loading dye
  • Well 4 : 5µL of RBS-FNR Part I+1µL of 6X loading dye
  • Well 5 : 5µL of FNR Part I+1µL of 6X loading dye
  • Well 6 : 5µL of FNR Part II+1µL of 6X loading dye
  • Well 7 : 5µL of BphR2 Part II+1µL of 6X loading dye
  • Gel : 1%

Expected sizes :

  • PSB1C3 : 2070 bp
  • RBS-BphR2 Part I : 197 bp
  • BphR2 Part II : 790 bp
  • RBS-FNR Part I : 615 bp
  • FNR Part I : 597 bp
  • FNR Part II : 200 bp

We obtain fragment at the right size for RBS-BphR2 Part I, BphR2 Part II, RBS-FNR Part I, FNR Part I, FNR Part II but not for PSB1C3. We will do a digestion of PSB1C3 by DnpI to clean it.

2 - Digestion of PBB1C3 by DnpI

XiaoJing

Used quantities :

  • PSB1C3 : 17µL
  • Buffer : 2µL
  • DnpI : 1µL

We keep the digestion for 1h30 at 37°C.

3 - Electrophoresis of the digestion of PSB1C3 by DnpI

XiaoJing

[[]]
  • Well 1 : 6µL DNA ladder
  • Well 2 :
  • Well 3 : 20µL of PSB1C3 digested by DnpI+4µL of 6X loading dye
  • Gel : 1%

Expected sizes :

  • PSB1C3 : 2070 bp

We obtain fragment at the right size for PSB1C3. We will purify it. We used an electronic eppendorf gun too fast, some product get up and fill from well 3 to well 4 and 5.
