Extraction of AgA1P from yeast genome with BSAI
AGA1P was extracted with BSAI overhangs for subsequent cloning from W303 and BY4000, according to Looke et al., PMC 2011.
Protocol:
- 1) Resuspend one yeast colony in 100 µl of 200 mM LiAc, 1% SDS solution and incubate at 70°C
- 2) Add 300 µl of 36% ethanol and vortex
- 3) Spin down DNA at 15 000 g for 3 minute
- 4) Wash pellet with 70% ethanol
- 5) Disolve pellet in 100 µl of water and spin down debris at 15 000 g for 15 seconds

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

The 2 plates put into the incubators showed 4 colonies at most.
We decided to wait for the plates to develop a bit more and to put back the miniculture and colony PCR to Monday 27th 2015. Meanwhile, after a few hours into the incubator, plates were wrapped with parafilm and put into the fridge at 4°C.

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).
