    • There is described a method for producing a preparation having a high content of Factor VIII (AHF), i.e. with a specific activity of at least 1.5 units of Factor VIII/mg protein, immunoglobulin G (IgG) of from 15 to 30 mg/1000 units of Factor VIII and fibrinogen of from 20 to 40 mg/100 units of Factor VIII. The method consists in that a Factor VIII containing plasma fraction is dissolved in a buffer, the solution is purified from undesired proteins by precipitation and is concentrated, the precipitation of undesired proteins being carried out in the presence of sulfated polysaccharide at a pH of from 6 to 7. After separation of the undesired proteins, a Factor VIII concentrate is precipitated, dissolved and processed into stable form. If desired, an antithrombin III-heparin complex or an antithrombin III-heparinoid complex is added to the solution.
    • 描述了一种制备具有高含量因子VIII(AHF)的制剂的方法,即具有至少1.5单位因子VIII / mg蛋白质的比活性,15至30mg / 1000的免疫球蛋白G(IgG) 因子VIII和纤维蛋白原单位为20至40mg / 100单位因子VIII。 该方法包括将含有因子VIII的血浆级分溶解在缓冲液中,通过沉淀将溶液从不想要的蛋白质中纯化并浓缩,不需要的蛋白质的沉淀在硫酸化多糖的存在下进行,pH为6 在分离不需要的蛋白质之后,将因子VIII浓缩物沉淀,溶解并加工成稳定的形式。 如果需要,向溶液中加入抗凝血酶III-肝素复合物或抗凝血酶III-类肝素复合物。
