- ✓ Colony PCR: from EF-1α site directed mutagenesis plates, PCR w/ BioBrick primers
- ✓ Assembly: EF-1α into V0120
Colony PCR & BioBricking
> Pick colonies from site directed mutagenesis plates from 2/01 (6 each)
> Use Forward EF1a/ Reverse EF1a (contain Xba and Pst ends)
> Cut products with X/P (PstI leaves desired mutants in tact and cuts non-mutated fragments)
> Isolate 1184 bp band for cloning
PCR
1-6. Forward strand mutagenesis clones
7-12. Reverse strand mutagenesis clones
