title: Assessment of collagenase activity in cartilage.
abstract: Assay of collagenase activity involves the use of radiolabeled collagen. Stimulation of cartilage with proinflammatory cytokines results in the upregulation of collagenases and the subsequent release of degraded collagen fragments. These enzymes can be localized in both osteoarthritic and rheumatoid arthritis cartilage and synovial tissues.
