Collagenase NB 8 Broad Range-The Extra Push

For Cell Isolation of Rodent Pancreas and Tumors

Collagenase NB 8 Broad Range is a chromatographically purified enzyme resulting in a high collagenolytic activity. This product has an increased collagenase activity compared to Collagenase NB 4 Standard GradeCollagenase NB 4G Proved Grade and Collagenase NB 7D Gentle Grade. The additional enzymatic activities like clostripain, trypsin-like activity and neutral protease, as well as the endotoxin level are reduced. Collagenase NB 8 is suitable for a broad range of different applications in tissue dissociation such as isolation of rodent pancreatic islets of Langerhans, human cardiomyocytes, tumor cells, muscle cells, osteoblasts and porcine hepatocytes.
