Popis: The F(ab)₂ Fragmentation kits are designed for the generation and isolation of F(ab)₂ fragments from IgG molecules. The kit utilises Immobilised Pepsin resin. Pepsin is a proteolytic enzyme that is routinely used for the generation of F(ab)₂ fragments from immunoglobulin G (IgG). One or more of the disulfide bonds that join the heavy chains in the hinge region are preserved, so the two Fab regions of the antibody remain joined together, yielding a divalent molecule (containing two antibody binding sites), hence the designation F(ab)₂. The light chains remain intact and attached to the heavy chain, whereas the Fc fragment is digested into small peptides. The Immobilised Pepsin offers the distinct advantage of eliminating enzyme contamination of the F(ab)₂ fragments.

Popis: 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.

Popis: FOCUS™ PhosphoRich™ is a ready-to-use kit that enriches phosphorylated proteins and phosphopeptides from complex biological samples. The kit contains spin columns that have a phosphoprotein binding resin with a binding capacity of ~20 mg phosphorylated ovalbumin per column. The resin columns supplied with the kit can be reused, if regenerated and stored properly. FOCUS™ PhosphoRich™ is suitable for 2D gel electrophoresis and for proteomics and cell signalling studies.

Popis: FOCUS™ Global Fractionation kit is designed to fractionate complex biological samples into cytosolic and membrane fractions. The resulting membrane fractions are subsequently fractionated into either peripheral and integral membrane proteins or lipid raft associated proteins and detergent soluble membrane proteins.

Popis: 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.

Popis: 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.

Popis: 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).
