Collagenase NB 4G Proved Grade-Extra Side Activities
For Isolation of Hepatocytes, Fibroblasts and Epithelial Cells
Collagenase NB 4G Proved Grade is an enzyme mixture which contains collagenolytic and additional enzymatic activities including clostripain and neutral protease. The ratio of these activities leads to gentle and efficient tissue dissociation. The product is suitable for isolation of a broad variety of cell types, especially for fibroblasts, human and rodent hepatocytes, frog oocytes and epithelial cells.
