Abstract
A simple, rapid, sensitive, and specific film assay for collagenase activity employing a glass-supported, reconstituted collagen gel is described. Digestion of the collagen film results in sharply defined zones of lysis detectable by staining with Coomassie blue. The assay is semiquantitative and suitable for micro enzyme determination in biological fluids.
