    摘要: The method for the aptitude testing of protein fractions containing factor VIII the further processing of which comprises a pasteurizing step is performed in such a way that the starting material is examined for fragments within a range of from 20 to 50 kD. Fragments of factor VIII within this range evidently cause inhibitor formations in patients pretreated with factor VIII. Batches contaminated with such fragments can also be utilized, i.e., for the preparation of a high purity virus-free factor VIII by size exclusion chromatography on hydrophilic materials.
