Thermo Scientific™ B-PER™ Bacterial Protein Extraction Reagent

Description

• Perform efficient, gentle lysis and extraction of E.coli and other bacterial cells with Thermo Scientific™ B-PER Bacterial Protein Extraction Reagents
• These easy-to-use cell lysis reagents are nonionic detergent solutions that effectively disrupt cells and solubilize native or recombinant proteins without denaturation
• Certain formulations include DNase I and lysozyme enzyme supplements to improve yield of large molecular weight proteins that are difficult to purify
• B-PER Reagents are compatible with the addition of standard protease inhibitors and with downstream protein purification methods, such as GST purification and His-tagged immobilized metal affinity chromatography (IMAC)
• Highlights: Ready to use – B-PER Reagents provide one-step E.coli cell lysis by a mild, nonionic detergent (proprietary) in your choice of Tris or phosphate buffer formulations Fast and simple – just add B-PER Reagent to a bacterial pellet, shake for 10 minutes and recover soluble proteins after pelleting the cell debris Excellent yields – recover both soluble and insoluble recombinant protein from bacterial lysates and purify inclusion bodies to near-homogeneous levels Flexible – B-PER Reagents are suitable for any scale of protein extraction and are available in phosphate and 1X and 2X Tris formulations, with and without enzymes Compatible – completely compatible with addition of protease inhibitor cocktails, and resulting protein extract can be used in protein assays, typical affinity purification methods (e.g., GST, 6xHis) and other applications Convenient, ready-to-use formats: B-PER and B-PER II (2X) Reagents are free of enzymatic components B-PER Reagent (in phosphate buffer) is an amine-free formulation for direct compatibility with labeling and crosslinking B-PER with Enzymes and B-PER Direct with Enzymes include lysozyme and DNase I for improved lysis and recovery Includes: Reagent packages are available in Tris and phosphate buffer formulations; Kits contain Tris-based B-PER Reagent plus lysozyme and DNase I enzymes.
