OVA2 (pYGG2) E. coli transformation results
Previously (see 2015-07-21) plates were put overnight into incubators at 37°C.
There is no colonies on the plates, either because the E. coli mix died before being plated or because the golden gate failed in some ways. The latter hypothesis is unliky as we woµld have red negative colonies onto the plate.
=> It turns out we did not use the right plasmid. We shoµld have used pYGG1

We started taking care of our biobricks ! We planned to deposite four biobricks : DEC205, OVA2, IFNgamma and Mat alpha IFN gamma. For OVA2 and DEC205, we just amplified the fragments with primers designed to make the fragment fit into the pSB1C3 plasmid. For IFN gamma and Mat alpha IFN gamma, as IFN gamma presented a restriction site, we proceeded to do a site directed mutagenenis to remove it. Mutagenesis of IFNgamma and Mat alpha IFN gamma: We performed two consecutive PCR, the first one (PCR1) to introduce a mutation at the desired site and the second one (PCR2) to amplify the entire fragment (see 21/08). In between, PCR clean-ups were done using Nucleospin Gel and PCR Clean-up (LOT :1504/001).
