title: Degradation of type I and II collagen by human activated C1-s.
abstract: The activated first component of human complement, C1-s, was shown to cleave type I and II collagen and gelatin. The proteolytic activity was heat labile and was inhibited by a monoclonal antibody (M241) which recognized light chain of active human C1-s or by a serine protease inhibitor, DFP, but not by a chelating agent.
