Results of the last transformation

2 red colonies (which is weird)
Liquid culture for amplification

PCR fragments quantification

Expected results

Results

We get expected bands but, as for second PCRs of VVD and YN155 fragments, bands 2 time heavier than expected bands appeared

We get an amplification of pDawn independent of the temperature

Expected results

Results

After the last Gibson reaction we have get red colonies that should correspond to bacteria transformed with pSB1C3-RFP (which should be impossible after the gel migration and purification). So we analyzed the content of the gel extraction and we saw that the tube only had linearized backbone. About pDawn III PCR 2, the migration of 5 µl from the gel extraction of PCR products have shown that there is not a high quantity of DNA material, not enough for a Gibson assembly…
