The Yeast Protein Kit is a simple and convenient method for the rapid and thorough lysis of yeast cells. The kit has been optimized for use with S. cerevisiae and C. albicans but can be used for any fungal species that is susceptible to yeast lytic enzyme digestion. The digestion procedure effectively generates spheroplasts of yeast cells, making them ideal for both protein and DNA analyses including Western blotting and PCR, respectively.
