2,5 µl Oligo_F
2,5 µl Oligo_R
1µl template
1 µl Phusion
50 µl qsp H2O (33µl)

PCR verification/Analysis

Analysis of PCR product (Gel 1)
Analysis of PCR product (Gel 2)

After the PCR :

  • 2*3µl have been analysed by electrophoresis
  • the other 44µl of PCR products have been purified by the Promega kit.


  • Electrophoresis

ladder : 10µl ladder 1 kb
samples : 3µl of PCR products + 2µl of Loading Dye
migration 30min at 100V, on a 1% agarose gel

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
