B-PER® Bacterial Protein Extraction Reagents are designed to extract soluble protein from bacterial cells. The B-PER® Bacterial Protein Extraction Kit eliminates the need for harsh mechanical procedures, like sonication. The easy-to-use cell lysis solution uses mild non-ionic detergents to disrupt cells and solubilise proteins without denaturation. Enzyme supplements such as DNase I and Lysozyme allow for improved yield of large molecular weight proteins which are difficult to purify. B-PER® is also compatible with downstream protein purification methods such as GST purification and His-tagged immobilised metal affinity chromatography (IMAC).

B-PER™ Complete Bacterial Protein Extraction Reagent is an all-in-one formulation of non ionic detergent and enzymes that enables mild extraction of proteins from both gram-negative and gram-positive bacteria without the need for mechanical disruption. B-PER Complete Reagent combines a universal nuclease and lysozyme to improve cell lysis and reduce viscosity, and may be used for soluble protein extraction and inclusion body purification from bacterial cell lysates.
