PCR

We performed PCR on to amplify the sequence in order to have enough amount of DNA to carry out the following of our experiments.


PCR amplification

Protocol

  • List of Oligos :

  • Preparation of the templates :
    Resuspension of 1 colony in 100µl of water.


  • Preparation of PCR mix :

For each sample,

1 µl dNTP
10 µl Buffer Phusion 5x
2,5 µl Oligo_F
2,5 µl Oligo_R
1µl template
1 µl Phusion
50 µl qsp H2O (33µl)

Culture of ligation transformants

  • 4 clones of each transformation were cultured in 7,5 mL LB + ampicilline. The colonies picked up were the rest of those already picked up from the transformation plate (for the PCR screening of August 8).
  • 37°C overnight
Ligation L128 L129 L130
Name pFlgA pFlgB pFlhB
Clone N° 1 2 3 4 1 2 6 7 1 2 7 8
Red fluorescence yes yes no no yes yes no no yes no no no
