Collagenase D Application Collagenase from C. histolyticum is used for the dissociation of tissues for the establishment of primary cell cultures. Collagenase D is recommended when functionality and integrity of cell-surface proteins are important. Product Description EC 3.4.24.3 Enzyme activity: Collagenase activity: >0.15 U/mg (according to Wünsch) (25°C, 4-phenyl-azobenzyl-oxycarbonyl-Pro-Leu-Gly-Pro-D-Arg as the substrate) Contaminating enzyme activities: trypsin, clostripain, and total proteolytic activity Collagenase D has a normal to high collagenase activity and very low tryptic activity (usually <0.2 units/mg, BAEE as substrate). Inhibitors: Collagenase inhibitors: EDTA, EGTA, Cys, His, DTT, 2-mercaptoethanol Collagenase is not inhibited by serum. Clostripain inhibitors: TLCK Trypsin inhibitors: aprotinin, trypsin inhibitor (egg white, soybean) Specificity: Collagenase degrades native collagen. Clostripain, trypsin-like enzymes, and neutral proteases degrade other proteins as well. Working concentration: 0.5 - 2.5 mg/ml |
