Wet Lab: OmpF/C promoters characterization

Electrophoresis Gel OmpF PCR_TaqDNApol

In order to probe the PCRs reactions an electroforesis gel was made. This was loadded as follows:

  • Ladder
  • positive control B3K3
  • B3K3 OmpF
  • positive control B1T3
  • B1T3 OmpF









The reactions for B1T3 were sucessful. The next step is to repeat the PCR reaction with the same protocol but this time using the RTTH enzyme.

Oligo Design: GFP suffix FWD

>BBa_E0240 FWD

5'- GCT CTA GAG c TCA CAC AGG AAA GTA CTA GAT GCG -3'

  • Length: 24
  • GC content 45.8%
  • MeltTemp: 56.4ºC


This primer was desinged to amplified an expression plasmid [OmpFp + GFP]
