Monday 12th July Lab work Getting DNA closer Amplification of DS-TDcasN-, DS-SPcasN- and pZA21 plasmids By Caroline
Plasmids extracted the 4/07/16 were used to amplify the dCas9 needed for the get DNA closer tool and the pZA21 plasmid in which the tool will be inserted. A PCR was carry out using Q5® High-Fidelity 2X Master Mix and following the usual protocol adapted to have 50µL at the end.
Electrophoresis of the PCR amplification By Caroline
5µL of the amplifications are mixed with 1µL of purple loading dye. The solutions are put into a 0.8% agarose gel and migrated for 30min.
Liquid culture of transformed NM, TD, ST1 and SP cas9 By Mathilde and Laetitia
Two colonies from each petri dishes were cultured in 1mL of LB and Spectinomycin (50µg/mL).
Our 8 cultures were put in incubation at 37°c, 180 rpm OV.
Biobrick characterization Electrocompetents and transformation by electroporation of BL21 By Charlene
Cells transformed on 11/07/16 grew overnight. However no colony was observed.
To control if there is a bacteria transformed which was not put on Petri dish, we performed another experiment. 100 µL (500µL concentrated) of transformed bacteria for each condition, conserved at -4°C from yesterday, were split in 3 solutions :
30µL of bacteria + 3mL LB + Streptomycin (50µg/mL) + Chloramphenicol (30µg/mL)
30µL of bacteria + 3mL LB + Streptomycin (50µg/mL)
30µL of bacteria + 3mL LB + Chloramphenicol (30µg/mL) Cells were incubated for 8h at 37°C, 200 RPM.
No bacteria grew so we concluded that there was a problem with the transformation.
Visualization Transformation of gBlock 4.2 pPS16_008 'By Laetitia and Mathilde
The gBlock 4.2 in the plasmid pPS16_008 was transformed with DH5α chimio competent cells following the protocol from the 11/07/2016.
Petri dishes peparation (x3) :
10µL of Ampycillin (50µg/mL)
5µL of Xgal (0,25µL/mL)
2µL of IPTG (0,1µL/mL)
20 mL of LB+Agar The two gBlocks constructions were plated in duplicata (50µL and 150µL), and a controle construction was plated alone.
The plates were put in incubation at 37°c overnight.
