Amplification of Genes of interest (OmpR, EnvZ, FlhDC)
We performed PCR on to amplify the sequence in order to have enough amount of DNA to carry out the following of our experiments.

- 50µl of Mix PCR by tube/clone
- one toothpick of each clone's colony by tube
- Program : Annealing 55°C - Time élongation 1'30" - Number cycle : 29
Conditions of electrophoresis
- 10µl of ladder 100 pb
- 10µl of screening PCR
- migration ~30min at 100W on 1,5% gel
- Program PCR "Screening": Annealing 55°C - Time élongation 1'30" - Number cycle : 29
Electrophoresis Purification of PCR
When the PCR cycles were finished,
conditions :
- 10µl of ladder 1 kb (unlike 100 pb)
- 2 x 30µl of PCR products added with 10µl of loading Dye 6x
- migration ~30min at 100W on a 1,5% agarose gel.

==> Conclusion:
- PCR of pFlgA, pFlgB and pFlhB have succeed, but we always have a problem with pFlhDC probably because of the oligos wich are not specific.
