Getting DNA closer Electrophoresis of PCR products DS_SPcasN, DS_TDcasN, pZA21 and pZA31 By Caroline PCR products obtained the 13/07/2016 were put to migrate for 30min in a 0,8% agarose gel. Migration of SP,TD, pZA21 and pZA31 Biobrick characterization LB culture of electro-transformed BL21 cells (Cf) By Mathilde Each transformation : pclTAA + K1372001, pcl_TAG + K1372001 and pcl_Tq + K1372001 was added to 3mL of LB and one or two antibiotics. Three conditions were tested for each transformation : 15µL of Chloramphenicol (30µg/mL) 5 µL of Streptomycin (50µg/mL) 15µL of Chloramphenicol (30µg/mL) + 5 µL of Streptomycin (50µg/mL) Cultures were put in incubation at 37°c, 180 rpm. Visualization Electrophoresis of PCR products pPS16_004 By Caroline PCR products obtained the 13/07/2016 were put to migrate for 30min in a 0,8% agarose gel Transformation of bacteria with pPS16_004 and pPS16_007 By Alice, Terrence and Mathilde PCR made on bacteria transformed with pPS16_004 and pPS16_007 did not give expected results. We supposed that bacteria used for these PCRs did not still have the plasmid of interest. That is why we performed another transformation of DH5α competent cells with pPS16_004 and pPS16_007. We transformed cells following this protocol. We add 5μl of sterile H2O to the ligation product rest and used the whole for the transformation. Finally, we spread cells on Petri dishes (LB + Amp 50μg/mL + xGal 0.25μL/mL + IPTG 0.1 μL/mL) in duplicate .
