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).

Antibody Fab and F(ab)₂ Fragmentation of Mouse IgG₁ Kits are designed for the generation and isolation of Fab and F(ab)₂ fragments from mouse IgG₁ molecules. The kit utilises Immobilised Ficin resin. Ficin (or Ficain) (~25000 Da) is a cysteine protease enzyme (EC 3.4.22.3) isolated from fig latex that has the endopeptidase activity to cleave immunoglobulin G molecules in the hinge region. Ficin has an effective range of pH 4 to 9,5 with an optimal pH of 6,5 and cleaves bonds that involve uncharged or aromatic amino acids. Ficin is typically used to cleave mouse IgG₁ as this is difficult to cleave with papain and pepsin. In the presence of 1 to 4 mM or 10 to 20 mM cysteine, ficin generates F(ab)₂ and Fab fragments respectively.

Specifically designed for yeast research and supplied with yeast specific reagents. Extracts and solubilises nearly all of the proteins from yeast, including membrane and soluble proteins. Extraction is based on gentle lysis of yeast cells with a yeast lytic enzyme preparation, LongLife™ Zymolyase®, which has improved stability and shelf life. Enzymatic action is followed by extraction of total proteome with the supplied strong chaotropic extraction buffer that solubilises even the most difficult proteins.

The 'critical micelle concentration' (CMC) of a detergent varies with temperature, pH, ionic strength, detergent concentration, purity and presence of organic agents in the detergent. Using a large excess of detergent may pose problems during purification procedures or other downstream applications.
