Digestion of plasmids

By Mathilde and Alice

The following plasmids were digested again with EcoR1 and HindIII using this protocol:

  • pPS16_001 (from the 6 clones that were selected on 29/06/16)
  • pPS16_003 (from the 6 clones that were selected on 29/06/16)
  • pPS16_005 (from the 6 clones that were selected on 29/06/16)
  • pPS16_006 (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 digestion products were mixed as follow to be migrated on an agarose gel.

Component Volume (µL)
Digested DNA 20
Loading buffer 3.3

The DNA concentration was still insufficient meaning the extraction step was not efficient.

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-ST1casN-
  • DS-TDcasN-

Then plasmids were digested with AvrII

Component Volume (µL)
Plasmid 10
Tango buffer 10x 2
Water 7
AvrII enzyme 1

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

Component Volume (µL)
Digested DNA 5
Water 5
Loading buffer 2
