Merck, V900893-1G, Collagenase from <I>Clostridium histolyticum</I>

General description
Collagenase from Clostridium histolyticum is a collagenolytic enzyme. It interacts with collagen-like substances and is responsible for the degradation of collagen into small peptides.
Application
Collagenase from Clostridium histolyticum may be used for the isolation of cells from many types of animal tissue. VETEC Collagenase Type IV has low tryptic activity. It is suitable for the digestion of islet cells from the pancreas.

Suitable for use in preparation of single cell suspension for sequencing.
Biochem/physiol Actions
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.
Analysis Note
Also contains clostripain, neutral protease, and tryptic activities.
Other Notes
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.
