Collagenase activity in human gingival fluid was measured using a radioactive collagen fibril assay. The activity was positively correlated with the severity of gingival disease. The fluid collagenase seemed to be controlled by alpha 2-macroglobulin, based on its activation by NaSCN, and to be present solely in the extracellular fraction. Examination of the collagen breakdown products by acrylamide gel electrophoresis indicated that the fluid collagenase was of tissue rather than bacterial origin.
