Collagenase NB 5 Sterile Grade-For Process Development

For Human ADSCs, Chondrocytes and Stem Cell Passaging

Collagenase NB 5 Sterile Grade is a natural enzyme mixture that contains collagenolytic and additional enzymatic activities including clostripain and neutral protease and is sterile according to European Pharmacopoeia. The balanced ratio of these activities ensures gentle and efficient tissue dissociation. Collagenase NB 5 is applicable to 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 their passaging, and rodent osteoblasts. This product is also part of our Translational Collagenase NB portfolio. It has enzymatic properties similiar to Collagenase NB 4 Standard Grade for use in research applications and Collagenase NB 6 GMP Grade for clinical applications like regenerative medicine and transplantation.

For initial testing and protocol optimization, Collagenase NB 4 Standard Grade can be used. If the application has to meet GMP requirements, Nordmark also offers Collagenase NB 6 GMP Grade which has comparable enzymatic properties to Collagenase NB 5 Sterile Grade and Collagenase NB 4 Standard Grade.
