Screening of the cloning of E0240 and FlhDC+promotor
We obtained single colonies with the dilution 100.
13 clones were analysed by PCR
PCR screening
reaction mixture (25 µL)
- 12,5 µL Quick load PCR Mixture 2X
- 0,5 µL O18
- 0,5 µL O19
- 11,5 µL water
PCR screening programm
- elongation time: 1 min 30
- primers: O18 and O19
- positive control: S158 (pSB3K3)
- negative control: no template
Electrophoresis

Results:
- The clone of E0240 (S159.1) always have several bands amplified by PCR. It might contain different plasmids.
- The clone of FlhDC+promotor (S161.1) don't have the correct size band. It also doesn't have the insert in the plasmid.
