    • A human Activated Protein C preparation with a high specific activity being substantially free from thrombin or an equivalent protease and/or Protein C not being subjected to activation and a process for preparing the same are provided. A human Activated Protein C preparation which shows specific activity of 3500 U/mg or more, the unit of specific activity being defined as an amount of APC which prolongs twice an activated thromboplastin time (APTT) of normal human plasma, and is substantially free from thrombin or an equivalent protease and/or Protein C not being subjected to activation. Said preparation is prepared by a process for purification of human Activated Protein C which comprises, after activation of Protein C with thrombin or an equivalent protease, contacting a solution containing human Activated Protein C with a cation exchanger to allow for adsorption of thrombin and Activated Protein C to the exchanger, and then eluting human Activated Protein C alone.
    • 提供具有高比活性的人活化蛋白C制剂基本不含凝血酶或未经活化的等同蛋白酶和/或蛋白质C及其制备方法。 表现出3500U / mg或更高的比活性的人活化蛋白C制剂,比活性单位被定义为延长正常人血浆活化凝血活酶时间(APTT)两倍的APC量,并且基本上不含 凝血酶或相当的蛋白酶和/或蛋白质C未受激活。 所述制剂通过纯化人活化蛋白C的方法制备,所述方法包括在用凝血酶或等效蛋白酶活化蛋白C后,使含有人活化蛋白C的溶液与阳离子交换剂接触以允许吸附凝血酶和活化蛋白 C加入交换器中,然后单独洗脱人活化蛋白C.
