    • A protease for activating the blood clotting factor VII, which is inhibited by the presence of aprotinin, is increased in its activity by calcium ions and/or heparin or heparin-related substances, and in SDS-PAGE, on subsequent staining in the non-reduced state, comprises one or more bands in the molecular weight range from 50 to 75 kDa; and in SDS-PAGE, on subsequent staining in the reduced state, comprises a band at 40 to 55 kDa, one or more bands in the molecular weight range from 10 to 35 kDa, and a band in the molecular weight range between 60 and 65 kDa, which corresponds to a proenzyme. Pharmaceutical preparations containing the protease or its proenzyme are suitable for the prophylaxis and treatment of bleeding events, e.g. in the presence of FVIII inhibitors, wound healing and for the treatment of disorders which are caused by fibrin-containing thrombin.
    • 通过钙离子和/或肝素或肝素相关物质活化通过抑肽酶抑制的血液凝固因子VII的蛋白酶的活性增加,并且在SDS-PAGE中,随后在非 - 还原状态包含分子量范围为50至75kDa的一个或多个条带; 并且在SDS-PAGE中,在随后的还原状态染色中,包含40至55kDa的条带,分子量范围为10至35kDa的一个或多个条带和分子量范围为60至65的条带 kDa,其对应于酶原。 含有蛋白酶或其酶的药物制剂适用于预防和治疗出血事件,例如, 在FVIII抑制剂的存在下,伤口愈合和用于治疗由含纤维蛋白的凝血酶引起的疾病。
