Investigating ADAMTS-mediated aggrecanolysis in mouse cartilage

Proteolysis of the cartilage proteoglycan aggrecan is a feature of arthritis. We present a method for analyzing aggrecanolysis in in vitro cultures of 3-week-old mouse femoral head cartilage based on traditional methods developed for large animal species. Investigators can choose either a simple analysis that detects several aggrecan fragments released into culture medium only or a more comprehensive study that detects all fragments present in...
