This is a protocol to lower the copy number of pGKL1 for directed evolution. Created by the luilab (www.liulab.com)
Yeast strain with "Dummy" polymerase and methionine promoter (MET3) integrated.
Yeast synthetic defined media
Methionine stock solution (2mg per ml)
- In a PCR tube, mix the components on ice in the order they are listed above.
- Perform thermocycling program
- 95 °C 5 min
- 95 °C 30 s
- TH 30 s
- 72 °C 1 min for each 1 kb PCR product
- Repeat steps 2-4 a total of 12-36 times (24 is standard).
- 72 °C 5 min
