Construction of OmpR*+RBS and EnvZ*+RBS

I did some digestions (today), ligations (tommorow) and screening (the day after tommorow). I tried to build : RBS (B0034) + OmpR* and RBS (B0034) + EnvZ*

Protocol

Digestion name Template DNA Enzymes Volume of DNA
D 158 MP 155.1 - OmpR* XbaI - PstI 5 µL
D 159 MP 156.1 - EnvZ* XbaI - PstI 5 µL
D 102 MP 100 - B0034 SpeI - PstI 5 µL
  • X µL of Template DNA
  • Buffer (n°2) 10X : 3µL
  • BSA 100X : 0.3µL
  • Pure water qsp 30 µL
  • 1 µL of each enzyme
  • Incubate during about 3h at 37°C, then 20 minutes at 65°C (to inactivate the enzymes). Then 10°C overnight.

Creation of a registry of pFliL, pFlhDC, and FlhDC

Transformation of the ligations we did yesterday

We transformed L 143, L 144 and the negative controls T1 and T2, using Invitrogen's TOP10 chemically competent cells standard protocol.

Digestions

After having succeded in amplifying the promoter and the gene of flhDC, we decided to clone it into a plasmid. The first step is the digestion.
