Getting DNA closer

Glycerol stocks for DH5α tra,sformed with DS-NMcas, DS-SPcasN-, DS-ST1casN- and DS-TDcasN-

By Laetitia

8 stocks were made: 2 clones (Cl 1 and Cl 2) by cas:

  • Cl1 and Cl2 of DS-NMcas
  • Cl1 and Cl2 of DS-SPcasN-
  • Cl1 and Cl2 of DS-ST1casN-
  • Cl1 and Cl2 of DS-TDcasN-


For 1 glycerol stock:

  • 1mL of liquid culture
  • 500 μL of glycerol 60%



Biobrick characterization

BL21 electrocompetent cells preparation and transformation

By Mathilde and Charlène

We did an electro-transformation of BL21 with :

  • pcl_TAA + K1372001 (time constant equal to 5.9ms)
  • pcl_TAG + K1372001 (time constant equal to 6 ms)
  • pcl_Tq + K1372001 (time constant equal to 6 ms)

Cells were displayed on LB + Streptomycin (50µg/mL) + Chloramphenicol (30µg/mL) medium. For each condition, we made a dish with 50µL of cells and another with 500µL of cells.

PCR of DH5αlpPS16_008 with Dream Taq

By Laetitia

Preparation of the PCR mix (total of 200μL ):

  • 20 μL of Dream Taq Green Buffer
  • 20 μL of dNTP (10 mM)
  • 8 μL of primer 1151 (10 mM)
  • 8 μL of primer 1152 (10 mM)
  • 1,04 μL of Dream Taq
  • 142,96 μL of Nuclease free water

Divide up the PCR mix in 7 PCR tubes: put 25 μL of the mix in each tube.
