摘要：
An object of the present invention is to provide a novel prothrombin activator. The application of the activator to thrombin-related diseases is expected.Described is a prothrombin activator derived from snake venom, which is a calcium requiring type and comprises three polypeptide chains composed of one heavy chain having a molecular weight of about 62,000 or about 60,000 and two light chains having molecular weights of about 17,000 and about 14,000, respectively.
