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.
