Lab work

A - Aerobic/Anaerobic regulation system

Objective : obtaining BBa_K1155003

1 - Extraction of BBa_K1155003 from DH5α

Damir, Nadia

Tranformation from 07/30/13 works. We will extract plasmid BBa_K1155003.

Protocol : High-copy plasmid extraction

We extracted plasmid from colony 9, 11 and 12. We eluted our extracted plasmid in 50µL H2O.

2 - Electrophoresis to check the extraction of BBa_K1155003

  • Well 1 : 6µL of DNA Ladder
  • Well 2 : 5µL of BBa_K1155003 from clone 9+1µl of 6X loading dye
  • Well 3 : 5µL of BBa_K1155003 from clone 11+1µl of 6X loading dye
  • Well 5 : 5µL of BBa_K1155003 from clone 12+1µl of 6X loading dye
  • Gel : 0.8%

Expected sizes :

  • BBa_K1155003 : 2734 pb

Estimated concentrations :

  • Clone 9 : 18ng/µL
  • Clone 11 :18ng/µL
  • Clone 12 : 18ng/µL

We obtain fragment at the right size (Clone 12 starts 5 min after the others). The extraction was good. We will digest it.

Objective : obtaining BBa_K1155007

1 - Digestion of BBa_I732017 by EcoRI/SpeI to check sizes of fragments

Damir, Nadia

Used quantities :

  • BBa_I732017 : 41µL
  • Buffer FD : 5µL
  • EcoRI : 2µL
  • SpeI : 2µL

We let the digestion at 1h30 at 37°C.

2 -Electrophoresis to check the digestion of BBa_I732017 by EcoRI/SpeI

Damir, Nadia

Psgel20208.jpg
  • Well 1 : 6µL of DNA Ladder
  • Well 2 et 3 : 5µL of BBa_I732017 digested by EcoRI/SpeI+1µL 6X loading dye
  • Gel : 0.8%

Expected sizes :

  • RBS-LacZ : 3093 bp
  • PSB1A2 : 2079 bp

We don't obtain fragments at the right size. We will digest BBa_KI732017 again.

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

Objective : obtaining FNR and BphR2 proteins

1 - Transformation of BphR2, FNR and RBS-FNR in DH5α
