生化机理	Clostridial collagenases are among the most efficient degraders of eukaryotic collagen known; saprophytes use collagen as a carbon source while pathogens additionally digest collagen to aid in host colonization. Has both tripeptidylcarboxypeptidase on Gly-X-Y and endopeptidase activities; the endopeptidase cuts within the triple helix region of collagen while tripeptidylcarboxypeptidase successively digests the exposed ends, thus clostridial collagenases can digest large sections of collagen. Catalytic activity: Digestion of native collagen in the triple helical region at Xaa-\|-Gly bonds. With synthetic peptides, a preference is shown for Gly at P3 and P1', Pro and Ala at P2 and P2', and hydroxyproline, Ala or Arg at P3'.
产品介绍	Collagenases from Clostridium histolyticum are proteolytic enzymes that cleave peptide bonds in the triple helical collagen molecule of human or animal tissue in situ. They are also referred as crude collagenases, because they consist of collagenase class I and class II, neutral proteases and clostripain in different ratios. The ratio of enzymatic activities can be altered enabling cell isolation from various tissue types. Collagenase NB 7D Gentle Grade is a partly purified collagenase that has slightly higher collagenase activity while containing lower tryptic activities. The product is intended for research use only. Specification Collagenase activity ≥ 0.2 U/mg (PZ acc. to Wünsch) Trypsin-like activities ≤ 0.2 U/mg (BAEE) Ratio Collagenase : Trypsin ≥ 3.0 Application Collagenase NB 7D Gentle Grade is suitable for dissociation of a broad variety of tissue types especially in cases where sensitive conditions are beneficial. Storage conditions Collagenase NB 7D Gentle Grade is provided as a lyophilized conditionspowder. It should be stored at +2 to +8 ℃ in a dry environment. Under these conditions the product is stable until the minimum shelf life stated on the certificate of analysis if repeated opening and closing of the vial is avoided. Instructions for use: General Collagenase NB 7D Gentle Grade is especially designed for isolation of sensitive cells (e.g. dendritic cells, diverse tumor cells) from human or animal tissues. The product exhibits slightly higher collagenase activity and low tryptic activities preserving cell-membrane receptors and other cell-surface proteins. Tissue dissociation Recommended starting concentrations for selected applications: Skin (mouse): 0.18 - 0.22 PZ U/ml Tumor cells (mouse): 0.50 - 0.60 PZ U/ml In general, the appropriate collagenase concentration depends on tissue type and origin as well as on the isolation procedure. Collagenase activity is at an optimum at 37 ℃ and pH 7.4. Working solution To prepare a working solution, the stock solution is diluted with buffer to achieve the required collagenase concentration. The working solu-tion must be constantly stored on ice until use. Inactivation and inhibitors The dissociation process can be reduced, e.g. by cooling down or dilution of the enzyme solution. Collagenase is reversibly inactivated at high pH values and irrevers-ibly inactivated at low pH values. Inhibitors of collagenase include cysteine or chelating agents like EDTA. Important note Collagenase NB 7D Gentle Grade is intended for research use only.
