The Easy Yeast Plasmid Isolation Kit provides a simple and efficient miniprep method for rescuing plasmid DNA from yeast (Saccharomyces cerevisiae). The protocol uses Zymolyase for highly efficient enzymatic disruption of yeast cell walls, followed by SDS/alkaline lysis of the resulting spheroplasts. A spin column is used to purify the plasmid DNA which can then be transformed into E. coli for propagation and scaled-up plasmid preparations, or used as a template for PCR.
