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.

Lipid rafts are membrane microdomains that are enriched in caveolin, cholesterol, glycolipids, sphingolipids and glycosyl-phosphatidylinositol. Lipid rafts are also known as detergent-insoluble glycolipid-enriched complexes (GEMs) or DIGs. Many signalling proteins, including glycosylphosphatidylinositol (GPI)-anchored proteins, doubly-acylated tyrosine kinases of the Src family, and transmembrane proteins, are located in lipid rafts. Lipid raft localised proteins have been shown to be involved in intracellular membrane trafficking and signalling.
