Laboratory Notebook

A laboratory notebook is our real time record of our expriments. It porvides a detailled record of exactly what we do in the laboratory to obtain our experimental results. It documents our hypotheses, experiments and initial analysis or interpretation of our experiments. Moreover, we also mentionned the name of exprimenters and the place of our experiments. The protocols that we follow are available on protocols page: Protocols

The band on the gel are correct but there is a lot od DNA on the top of the gel and the secnd band is very weak. Morover, the sequence we ordered for otsB is wrong, so we need to correct it by PCR. So we will ordered primers and we’ll send to sequence after the PCR. For otsA, we’ll make an other transformation to select only one pure clone
