YeastBuster® Protein Extraction Reagent (for yeast cell lysis)

Description

YeastBuster™ Protein Extraction Reagent is formulated for a fast, efficient and gentle extraction of active proteins from yeast cells. The reagent avoids harsh conditions of vigorous mechanical or chemical treatment that often result in heat degradation of target proteins. The proprietary formulation utilizes a mix of mild detergent, protein stabilization buffer, and tris(hydroxypropyl) phosphine (THP) reducing agent (THP concentrate provided separately). This powerful combination eliminates the inconsistencies associated with tedious mechanical disruption of yeast cells with glass bead abrasives, ultrasonication and pressure disruption, or enzymatic digestion with β-1,3-glucanase lytic enzymes. The reagent has been tested with Saccharomyces cerevisiae, Pichia pastoris, P. stipidis, and Schizosaccharomyces pombe strains and with plant cells.

In practice, cells are harvested by centrifugation and suspended in YeastBuster. Following a brief incubation, insoluble cell debris is removed by centrifugation, and the clarified extract is ready to use. In addition to greater total protein yields in crude extracts and recovery of enzymatically active protein, the extracts are fully compatible with GST•Bind™ and Ni-NTA His•Bind® immobilized metal affinity chromatography (IMAC) purification methods. The reagent is available in 100- and 500-ml sizes.
