Transformation of Gblocks in DH5α

By Caroline and Lea

6 transformations were performed with the ligation products containing plasmids: pPS16_001, pPS16_002, pPS16_003, pPS16_004, pPS16_005, pPS16_006. 3 other transformations were performed with plasmids pPS16_007, pPS16_008 and pPS16_009 extracted the 30/06/16. TODOajouter le lien The transformation protocol were followed increasing plasmids quantities (5µL instead of 1µL). After transformation, cells are spread on petri dishes containing LB + Ampicillin (50µg/mL) + Xgal + IPTG.

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
