近十余年来,对于凝血因子的结构、功能和理化性质均有进一步的了解,对凝血因子的分离精制,也有不少的成果;出血性疾病的实验诊断,也逐步实现试剂的标准化和操作的仪器化,采用了电镜、色层分析、电泳和免疫化学技术,使许多研究已达到分子水平。在凝血因子方面,除已知的12种之外,1965年以来又 Nearly ten years, for coagulation factor structure, function and physicochemical properties have a better understanding of the clotting factor separation and refining, there are many achievements; experimental diagnosis of hemorrhagic disease, but also gradually realize the standardization and operation of reagents The instrumentation, using electron microscopy, color-chromatography, electrophoresis and immunochemical techniques, many studies have reached the molecular level. In the clotting factor, in addition to the known 12 species, since 1965 and again
