Yeast Protein Extraction Kit From Protein Discovery for Whole Proteome Analysis

KNOXVILLE, TN—September 1, 2010—Protein Discovery today announced that they have extended their protein extraction kit product line by launching the YPX Yeast Protein Extraction Kit. Unlike other yeast protein extraction products, the YPX kit does not use mechanical disruption to break open the tough cell walls of yeast. Using the YPX kit is much faster than carrying out conventional yeast lysis procedures used for protein extraction, and total protein yield is higher. The YPX kit protocol is simple and economical, and therefore offers substantial usability and cost benefits to researchers who wish to carry out experiments on many yeast cultures simultaneously. Finally, the YPX Yeast Protein Extraction Kit extracts the entire yeast proteome with nearly complete efficiency, and is uniquely compatible with quantitative yeast proteomics workflows which would otherwise be complicated by day-to-day and lab-to-lab variations in protein extraction efficiencies.

“We have developed a protocol that requires no mechanical disruption, no ice-water, only two buffers, and very short incubation periods,” said Jeremy Norris, PhD, vice president of research and development at Protein Discovery. “Extraction is unbiased and extremely efficient, and it works on all yeasts grown in any medium. This kit is suitable for just about any yeast proteome work and will be especially appreciated by researchers exploring the yeast membrane proteome or studying individual low-abundant proteins,” added Dr. Norris.

The economical YPX Yeast Protein Extraction Kit contains sufficient material to extract proteins from 150 grams of spun-down, wet cell pellet yeast culture harvests. Starting material can be frozen or freshly harvested.
