Platelets were studied for the presence of antithrombin (thrombin amidolytic inhibitory) activity. Platelet rich plasma contained more antithrombin activity than platelet poor plasma. This activity could be washed from a platelet pellet. Antithrombin activity increased on sonication of platelets but not following aggregation. Platelets contain antithrombin activity connected with the membrane and not involved with the release reaction.
