Protéines extraction

Protein extraction kits provide a simple, rapid, and reproducible method for preparing total cellular protein extracts from a wide variety of biological samples. The results of these extraction systems generate protein samples that can be applied directly to a variety of applications. High-performance models are designed for efficient recovery of genomic DNA and RNA. These extraction kits are capable of purifying genomic DNA, total RNA, and total protein simultaneously from cultured cells, animal tissues, whole blood, and biological fluids.

Bacterial Protein Extraction Kits, B-PER™

Bacterial Protein Extraction Kits, B-PER™

Supplier: Thermo Fisher Scientific

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).

Protein fractionation kit, FOCUS™ signal proteins

Supplier: G-Biosciences

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.

Antibody Fab and F(ab)₂ fragmentation of mouse IgG₁ kits

Antibody Fab and F(ab)₂ fragmentation of mouse IgG₁ kits

Supplier: G-Biosciences

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.
