Lab work

Biobrick characterization

Electrocompetents and transformation by electroporation of BL21

By Charlène

BL21 cells were grown up to OD600nm=7.14. They were then made competent and transformed with K1372001 extracted from clone 2 and pcl_TAA, pcl_TAG or pcl_Tq to create the following strains:

  • BL21|K1372001+pcl_TAA
  • BL21|K1372001+pcl_TAG
  • BL21|K1372001+pcl_Tq


Bringing DNA closer

DH5α transformation with DS-NMcas, DS-SPcasN-, DS-ST1casN- and DS-TDcasN-

By Laetitia and Mathilde

DS-NMcas, DS-SPcasN-, DS-ST1casN- and DS-TDcasN- plasmids were resuspended with 5μL of sterilized water. 5 tubes were prepared :

  • one control tube with only 50μL of DH5α heat-shock competent cells
  • four tubes with 50μL of DH5α heat-shock competent cells + 1μL of plasmid

The regular heat-shock competent cells transformation protocol was used.

Petri dishes preparation :

  • 200mL of LB Agar
  • 130μL (50μL/mL) of spectinomycin

Transformed cells were plated in duplicata (10μL and 50μL) on 8 plates. Control cells were plated on another plate.
