Brief Product Information

Collagenase NB 8 Broad Range
This product is characterized by a high collagenase activity (≥ 0.9 PZ U/mg) and reduced levels of proteolytic side activities.

Collagenase NB 7D Gentle Grade
This product is characterized by slightly higher collagenase activity with low tryptic activities ideal to preserve cell-surface proteins.

Collagenase NB 4G Proved Grade 
This product has a collagenase activity of ≥ 0.18 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. It is also available as GMP conformant Neutral Protease NB GMP Grade.

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.
