Well 1 : we have done one digestion so we have to obtain one fragment, we have two stripes, the digestion of Bba_K1155000 by SpeI wasn't good. Well 2, 3, 4, 6, 7 : we obtain NarG, NarK and NirB in PSB1C3 and Pfnr, NarK fragments at the right size, we can purify it. Well 8, 9 : we have done two digestions so we have to obtain two fragments, we have only one stripe, the digestion of Bba_K1155005 and Bba_K1155004 by EcoRI/SpeI wasn't good.

  • Thanks to electrophoresis we separated all the quantity of our digestion.

Nanodrop :

  • RSB-LacZ-Term : 59.6ng/µL
  • RBS-AmilCP-Term : 28.7ng/µL

WE obtain few quantities of plasmid that's why we will make an Ethanol precipitation to concentrated it.

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

Objective : obtaining FNR and BphR2 proteins

1 - Gibson assembly

Used quantities :

  • RBS-BphR2 :
    • PSB1C3 : 3µL
    • BphR2 Part I : 1µL
    • BphR2 Part II : 1µL
    • Gibson mix : 15µL ???????????????

    • Gisbon mix : 15µL ???????????????
  • RBS-FNR :
    • PSB1C3 : 3µL
    • RBS-FNR Part I : 1µL
    • FNR Part II : 1µL
    • Gibson mix : 15µL ????????????

We let these mix at 50°C during 1h. Then we the these mix at 4°C during the week end.

2 - Electrophoresis of PCR products : BphR2 Part I

Damir

  • Well 1 : 6µL DNA Ladder
  • Well 2 : 5µL of BphR2 Part I+1µL of 6X loading dye

  • Well 1 : 6µL DNA Ladder
  • Well 2 : 5µL of BphR2 Part I+1µL of 6X loading dye
  • Well 3 : 5µL of BphR2 Part I+1µL of 6X loading dye

Expected sizes :

  • BphR2 Part I : 178kb

On the first gel, all deposits disappear so we did the electrophoresis again. On the second gel, we didn't obtain stripes at the good size. We do the PCR again using new quantities and a new PCR program.

Used quantities :

  • Oligo 54F : 2µL
  • Oligo 55R : 2µL
