Application

This product is suitable for the disaggregation of human tumor, mouse kidney, human adult and fetal brain, lung and many other epithelia tissues. It has also been shown to be effective in liver and kidney perfusion studies, digestion of pancreas, isolation of nonparenchymal rat liver cells and hepatocyte preparation. Collagenase has also been used in the preparation of arterial tissue for the study of Advanced Glycosylation End Products. This enzyme has been tested for the release of heptatocytes at a concentration of approximately 1 mg/mL. Concentrations for digestion range from 0.1 to 5 mg/mL.

Suitable for use in preparation of single cell suspension for sequencing.

Actions biochimiques/physiologiques

La collagénase est activée à l′aide de quatre atome-grammes de calcium par mole d′enzyme. Elle est inhibée par l′acide éthylèneglycol-bis(bêta-aminoéthyléther)-N,N,N′,N′-tétraacétique, le bêta-mercaptoéthanol, le glutathion, l′acide thioglycolique et la 8-hydroxyquinoline.
The collagenase product is a mixture of enzymes secreted by C. histolyticum, with different products differentiated by the relative ratios of the 10-18 components found in the secreted enzymes. The main components are two collagenases, clostripain, and a neutral protease. The synergistic action of these enzymes degrade collagen and other intracellular materialThe action of both collagenase enzymes and the neutral protease is necessary for effective release of cells from tissue. Various types of collagen are the natural substrates for collagenase.

Attention

As supplied, this product is stable for one year at -20°C. There is no loss in FALGPA or protease activity in 30 days at 37°C, 50°C and -20°C. Solutions of crude collagenase are stable if frozen quickly in aliquots (at 10 mg/mL) and kept frozen at -20°C. Further freeze-thaw cycles will damage the solution. The product retains 100% activity over 7 hours when held on ice.

Définition de l'unité

Une unité de digestion de collagène (UDC) libère une quantité de peptides à partir du collagène d′un tendon d′Achille de bovin équivalant, en termes de couleur avec la méthode à la ninhydrine, à 1,0 μmole de leucine en 5 heures à pH 7,4 et à 37 °C en présence d′ions calcium. Une unité d′hydrolyse de FALGPA hydrolyse 1,0 μmole de furylacryloyl-Leu-Gly-Pro-Ala par minute à 25 °C. Une unité de protéase neutre hydrolyse la caséine et produit une couleur équivalente à 1,0 μmole de tyrosine en 5 heures à pH 7,5 et à 37 °C. Une unité de clostripaïne hydrolyse 1,0 μmole de BAEE par minute à pH 7,6 et à 25 °C en présence de DTT.

Notes préparatoires

Solutions are typically prepared at 1-2 mg/mL in TESCA buffer (containing 50 mM TES, 0.36 mM Calcium chloride, pH 7.4 at 37°C. This product also contains clostripain, nonspecific neutral protease and tryptic activities.

Protocoles

Enzymatic Assay of Collagenase (EC 3.4.24.3) using FALGPA (N-(3-[2-Furyl]acryloyl)-Leu-Gly-Pro-Ala)

To measure collagenase activity, N-(3-[2-Furyl]acryloyl)-Leu-Gly-Pro-Ala is used in a continuous spectrophotometric rate determination at 345 nm. Collagenase hydrolyzes collagen peptide bonds.
