A chromatographic method for collecting blood coagulation factor VII (Factor VII) and/or activated blood couagulation factor VII (activated Factor VII) from plasma-derived fractions with high yield is provided. In accordance with the method of the present invention, Factor VII and/or activated Factor VII of interest can be collected with a recovery rate of as high as 90% or more by letting Factor VII and/or activated Factor VII which fails to be adsorbed to a first anion exchange resin and remains in a non-adsorption fraction be adsorbed in a second anion exchange resin.
本发明提供了一种从血浆衍生馏分中高产率收集血凝因子 VII(因子 VII)和/或活化血凝因子 VII(活化因子 VII)的色谱方法。根据本发明的方法,通过让未能吸附在第一阴离子交换
树脂上并留在非吸附馏分中的因子 VII 和/或活化因子 VII 吸附在第二阴离子交换
树脂上,可收集到有关因子 VII 和/或活化因子 VII,回收率高达 90% 或更高。
