| + | After transformations, only white bacteria were selected (blue/white screen). They are expected to have plasmids with inserts of interest. PCR with DreamTaq DNA Polymerase is performed following [[Team:Paris_Saclay/Experiments#taqPCR|this protocol]]. Clones selected for PCR are kept on LB+Amp+XGal(2µLXGal/1000µLH2O)+IPTG(2µLIPTG/1000µLH2O). Two primers ([[Team:Paris_Saclay/Experiments#primers|1151_pheoR and 1152_pheoF]]) upstream and downstream the insertion site are chosen. Annealing temperature was 53°C. After amplification, 5 µL of each PCR products and 10 µL of DNA ladder were put on gel and migrated at 100v during 30 min. | ||

We used a high fidelity enzyme to reduce the error ratio and send to sequencing the PCR products. A PCR was carried out using Q5<sup>®</sup> High-Fidelity 2X Master Mix and following the [[Team:Paris_Saclay/Experiments#Q5PCR|usual protocol]] with pUC19 primers [[Team:Paris_Saclay/Experiments#primers|1151_pheoR and 1152_pheoF]]. |
