Digestion of plasmids

By Mathilde and Alice

The following plasmids were digested again with EcoR1 and HindIII:

  • 1.1 (from the 6 clones that were selected on 29/06/16)
  • 2.1 (from the 6 clones that were selected on 29/06/16)
  • 3.1 (from the 6 clones that were selected on 29/06/16)
  • 3.2 (from the 6 clones that were selected on 29/06/16)
Component Volume (µL)
Plasmid 10
Red buffer 10x 2
Water 7
EcoRI enzyme 0.5
HindIII enzyme 0.5

The mix was incubated at 37°C for 1 hour. An electrophoresis was done (0.8% of agarose).

Plasmids extraction

By Naiane and Laetitia

Plasmids from the following strains were extracted with the kit "Charge Switch-Pro Plasmid Miniprep":

  • DS-NMCas
  • DS-SPCasN
  • DS-ST1
  • DS-TDCasN

Then plasmids were digested with AvrII increasing the DNA quantity (10µL DNA, 1µL AvrII, 2µL Tango buffer, 7µL water). Digestion products were migrated (5µL digestion, 5µL water, 2µL Template:Font color
