Yeast protein extraction and purification has traditionally been difficult and time consuming because yeast cells contain a very complex cell wall, which is difficult to lyse. BioVision's EZLys? Yeast Protein Extraction reagent provides a simple and convenient method for highly efficient protein extraction from yeast strains. This Yeast Protein Extraction reagent eliminates the difficulties associated with traditional glass beads method and has been tested for use with different yeast strains like Pichia pastoris and Saccharomyces cerevisiae.
