Brief Product Information

Collagenase NB 6 GMP Grade
This collagenase has an activity of ≥ 0.1 PZ U/mg and a balanced mix of proteolytic side activities. It is manufactured according to GMP guidelines and sterile according to European Pharmacopoeia.

Collagenase NB 4 Standard Grade 
This product has an activity of ≥ 0.1 PZ U/mg and a balanced mix of proteolytic side activities.

Neutral Protease NB
This product is a protease from C. histolyticum. It has a proteolytic activity of ≥ 0.50 DMC U/mg.


Isolation Note

The suggested Nordmark Collagenase NB concentrations and isolation conditions should be regarded as starting points. Collagenase NB dosage is recommended in PZ units and DMC units for Neutral Protease NB to ensure consistent results.
