Collagenases and Neutral Proteases

Collagenases are enzymes that break the peptide bonds in collagen. 

Crescent Chemical Co., Inc. supplies the following  Nordmark Collagenases and Neutral Proteases from Clostridium Histolyticum for tissue dissociation. 

Nordmark is the worlds largest producer and supplier of Collagenases.
