Lab work

A - Aerobic/Anaerobic regulation system

((((((====Obtaining the PSB3K3 backbone plasmid====

1 - Electrophoresis of BBa_J004450 digested by EcoRI/Pst1 to check if the digestion was right

Damir, Nadia

IMAGE
  • Well 1 : 6µL DNA Ladder
  • Well 2 : 5µL of BBa_J004450 digested by EcoRI/Pst1
  • Gel : 0.8%

Expected sizes :

  • PSB3K3 : 2750kb
  • GFP : 1069kb 
We obtained fragments of the right size. Now we can purify the PSB3K3 plasmid.

2 - Gel purification of the PSB3K3 plasmid from BBa_J004450 digested by EcoRI/Pst1

2.1 - Migration of the remaining 45µL of BBa_J004450 digested by EcoRI/Pst1

  • Well 1 : 6µL DNA Ladder
  • Well 2 : 45µL of BBa_J004450 digested by EcoRI/Pst1
  • Gel : 0.8% 
Now we can do a gel purification of the highest band which contains the PSB3K3 plasmid.

2.2 - Electroelution of the highest band to extract the PSB3K3 plasmid from the gel

Nadia

Protocol : Electroelution 

We let the plasmid precipitate during the night.))))))))))))))))))))))

Objective : obtaining Bba_K1155007

1 - Colony PCR of Bba_K115007 in DH5α

Anaïs

Tranformation of 08/07/13 works. we will make a PCR Colony.

Colonie repiquée dans 10µL d'eau pour chaque tube ???????

Used quantities :

  • DNA : 2µL
  • Mix  : (it was divided in 25 tubes for each promotor with 23µL of mix in each on)
    • Oligo ... : 3.5µL
    • Oligo ... : 3.5µL
    • Buffer Dream Taq : 70µL
    • dNTP : 28µL
    • Dream Taq : 5µL
    • H2O : 590µL

PCR Program :

PsPcr808.jpg

2 - Electrophoresis to check the colony PCR products : Bba_K1155007

Anaïs, Damir

350px
  • Well 1 : 6µL DNA Ladder
  • Well 2 to 24 : 10µL of Bba_K1155007+2µL of 6X loading dye
  • Well 25 : 6µL DNA Ladder
  • Well 26 : 6µL DNA Ladder
  • Well 27 : 10µL of Bba_K1155007+2µL of 6X loading dye
  • Gel : 0.8%

Expected size :

  • Bba_K1155007 : 3583 bp

We obtain fragment at the right size for colonies 10, 14 and 15. We will extract BBa_K1155007.


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

Objective : obtaining FNR and BphR2 proteins

1 - Extraction of plasmid of BphR2, FNR, RBS-FNR

Damir

Transformation of 08/02/13 works. We will extract plasmids.

Protocol : Gel purification

We lost our plasmids. We will do the Gibson assembly again.

2 - Gel purification of RBS-BphR2 Part I

Nadia, XiaoJing

Protocol : Gel purification

We lost fragment. We will do the PCR again.
