Alkalmazás

Collagenase has been used in the preparation of arterial tissue for the study of advanced glycosylation end products (AGE). The enzyme has also been used along with other proteases for the disaggregation of human tumor, mouse kidney, human brain, lung epithelium and many other tissues. It is also effective in liver and kidney perfusion studies, digestion of pancreas, and isolation of nonparenchymal hepatocytes.

Biokémiai/fiziológiai hatások

Effective release of cells from tissue requires the action of both collagenase enzymes and the neutral protease. Collagenase is activated by four gram atom calcium (Ca2+) per mole enzyme. The culture filtrate is thought to contain at least 7 different proteases ranging in molecular weight from 68-130 kDa. Optimal pH ranges from 6.3-8.8. The enzyme recognizes the sequence -R-Pro-8-X-Gly-Pro-R-, where X is most often a neutral amino acid.
Collagenase is activated by four gram atom calcium per mole enzyme. It is inhibited by ethylene glycol-bis(beta-aminoethyl ether) - N, N, N′,N′-tetraacetic acid, beta-mercaptoethanol, glutathione, thioglycolic acid and 8-hydroxyquinoline.

Egység definíció

One collagen digestion unit (CDU) liberates peptides from collagen from bovine achilles tendon equivalent in ninhydrin color to 1.0 μmole of leucine in 5 hours at pH 7.4 at 37 °C in the presence of calcium ions. One FALGPA hydrolysis unit hydrolyzes 1.0 μmole of furylacryloyl-Leu-Gly-Pro-Ala per min at 25°C. One Neutral Protease unit hydrolyzes casein to produce color equivalent to 1.0 μmole of tyrosine per 5 hr at pH 7.5 at 37°C. One Clostripain Unit hydrolyzes 1.0 μmole of BAEE per min at pH 7.6 at 25°C in the presence of DTT.

Fizikai forma

Lyophilized powder containing calcium chloride

Elkészítési megjegyzés

A stock solution may be prepared by dissolving 0.05 - 0.1 mg of collagenase in one mL of 50 mM TES buffer containing 0.36 mM calcium chloride (TESCA), pH 7.4 at 37 °C. Use cold buffer.
Please note the material will not dissolve completely and few sediments may be seen. The sediments do not affect the activity of the solution.

Protocols

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.
