Chem. 333, 149-51 Collagenase NB 4G is a crude collagenase which contains collagenolytic and additional enzymatic activities including clostripain and neutral protease. The balanced ratio of these activities leads to gentle and efficient tissue dissociation.Suitable for isolation of a broad variety of cell types, especially for fibroblasts, human and rodent hepatocytes, frog oocytes and epithelial cells. Application Collagenase NB 4G is suitable for dissociation of a broad variety of tissue types. Specifications Contains class I and class II collagenase (1) and a balanced mix of neutral protease, clostripain and trypsin-like activities. Activity (Wünsch): ≥ 0.18 U/mg (Clostridiopeptidase A) EC 3.4.24.3 • Mr ca. 70 000 - 120 000 (collagenase) • CAS [9001-12-1] References and Definitions Unit 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.
