+ | <U> Aim:</U>In this part we wantant to proceed with the expression of our fusion protein containing the R5-CBD-BPA. To do this we need a cell line having a T7 RNA polymerase. The cells we chose were BL21De3 pLys S. These contain the T7 phage producing the T7 RNA polymerase, and lysozyme, which will inhibit the T7 RNA polymrase and help control the expression better in case our protein is toxic to the cells, and secondly in case the cells escape our control they will not be able to survive in nature, as they will lyse over time.</br></br> | ||
+ | <U> Protocol:</U> follow in this <a href="https://2016.igem.org/Team:Pasteur_Paris/Science">link</a></br></br> | ||
+ | <U>What we did in the lab:</U></br> | ||
+ | <U>Materials:</U></br>BL21De3 competent cells, SOC media, 42 °C waterbath.</br> | ||
+ | <U>Method:</U></br> | ||
+ | (I) : 50 µl of bacteria + 5 µl of pET43.1-C2 1.1</br> | ||
+ | (II) : 50 µl of bacteria + 5 µl of pET43.1-C2 1.2</br> | ||
+ | (III) : 50 µl of bacteria + 5 µl of pUC</br> | ||
+ | (IV) : 50 µl of bacteria + 5 µl of CT (plasmid given with the bacteria)</br></br></br> | ||
+ | After heat shock at 42°C, the cells were allowed to recover by growing at 37°C for 40 minutes in 150 µl of SOC, then the 200 µl of each sample were spread on a petridish with carbenicillin and grown at 37 °C for one night.</br></br> | ||
