This is a protocol to do PCR reactions on E. coli cells, directly after a transformation. (See here for colony PCR for yeast cells)
- Prepare mastermix
- Divide 19μl/sample over PCR reaction tubes/wells
- Prepare cells in water
- Add cell mixture to the mix
Re-suspend cells for each colony in 50μl DNAse free water and then add 1μl of this mix to the reaction.
