A simple protocol for easy PCR screening of P. pastoris transformants is described. In short, the P. pastoris cells are lysed with very small amount of the enzyme Zymolase and the crude cell lysate is directly used in PCR. This protocol needs no tube transfer steps and also obliviates the requirement of freezing the samples at -80°C before PCR screening. Because of a single step screenig, both overall and actual hands on time are considerably reduced.
