The collagenase is like tissue collagenases in that it cleaves collagen at a single site. The collagenase which has a molecular weight of about 50k daltons, specifically inhibits collagen-induced platelet aggregation, with substantially no effect on platelet count or size, and may be used alone or together with another platelet aggregation inhibitor. The latter may also be a leech-derived biochemical, such as an apyrase, or an inhibitor of the release of platelet aggregation factor by leucocytes. |
