Description
Collagenase NB 4 is a crude collagenase that contains collagenolytic and additional enzymatic activities including clostripain and neutral protease. The balanced ratio of these activities ensures gentle and efficient tissue dissociation. ApplicationCollagenase NB 4 is suitable for dissociation of a broad variety of tissue types.SpecificationsContains class I and class II collagenase (1) and a balanced ratio of proteolytic side activities.Activity (Wünsch): ≥ 0.10 U/mgSuitable for different applications in tissue dissociation such as isolation of human and rodent hepatocytes, chondrocytes, neuronal and endothelial cells, fibroblasts, cells from adipose tissue (e.g. ADSCs), stem cells and rodent osteoblasts.(Clostridiopeptidase A)EC 3.4.24.3 • Mr ca. 70 000 - 120 000 (collagenases) • CAS [9001-12-1]References and DefinitionsUnit definition: 1 U according to Wünsch (2) catalyzes the hydrolysis of 1 µmole 4-phenylazobenzyloxycarbonyl-L-prolyl-L-leucylglycyl-L-prolyl-D-arginine per minute at 25 °C, pH 7.1.References1.
