Construction of OmpR*+RBS and EnvZ*+RBS: Ligations

Cleaning of the DNA after the digestion

We used the QIAcube to wash the DNA, following the standard protocol.

Measure of DNA concentration of the digestion products

We used the biophotometer.
Settings:

  • 10 µL of template DNA in 50 µL of pure water
  • Blank : 10 µL of EB buffer in 50 µL of water.
Digestion name What's in ? Enzymes DNA C° (ng/µL)
D 158 OmpR* XbaI-PstI 12
D 159 EnvZ* XbaI-PstI 7
D 102 B0034 SpeI-PstI 16

List of ligations

  • We ligated the DNA following the standard protocol.
  • T5 is the autoligation control for L148 and L149.
Ligation name Insert name Vinsert µL Vector name VVector µL
L 148 (Amp) D 158 (OmpR*) 4 D 102 (B0034) 3
L 149 (Amp) D 159 (EnvZ) 7 D 102 (B0034) 3


Creation of a registry of pFliL, pFlhDC, and FlhDC

Analysis of the transformation we did yesterday

L143, L144, T1 and T2 showed no colonies. The positive control with pUC19 worked well.
We suppose that the ligation did not work. We will do it again today.
