    • A purification method of a high purified blood clotting factor IX is provided to improve specific activity of the blood clotting factor IX by removing impure proteins from the blood clotting factor IX through a series of purification procedures. The purification method of a high purified blood clotting factor IX comprises the steps of: subjecting cryopaste-free human serum to anion exchange chromatography; treating the active fraction of the anion exchange chromatography with solvent/detergent(S/D) so as to inactivate viruses; subjecting the S/D treatment product to anion exchange chromatography; subjecting the active fraction of the anion exchange chromatography to heparin affinity chromatography; subjecting the active fraction of the heparin affinity chromatography to cation exchange chromatography; and subjecting the active fraction of the cation exchange chromatography to nanofiltration so as to remove viruses.
    • 提供高纯化血液凝固因子IX的纯化方法,以通过一系列纯化方法从血液凝固因子IX中除去不纯的蛋白质来提高血液凝固因子IX的比活性。 高纯化血液凝固因子IX的纯化方法包括以下步骤:使无血清的人血清进行阴离子交换色谱; 用溶剂/洗涤剂(S / D)处理阴离子交换层析的活性部分,以使病毒灭活; 对S / D处理产物进行阴离子交换层析; 将阴离子交换层析的活性部分进行肝素亲和层析; 使肝素亲和层析的活性部分进行阳离子交换层析; 并对阳离子交换层析的活性部分进行纳滤,以除去病毒。

    • PURPOSE: Disclosed is a new DNA structure for tissue-specific expression of a blood coagulation factor consisting of the DNA encoding the amino acid sequence of the blood coagulation factor and the DNA encoding a promotor specific to the expression in hematopoietic cells, and useful for the genetic treatment of hemophilia B or the like. CONSTITUTION: The new DNA structure for tissue-specific expression of a blood coagulation factor consists of the DNA encoding the amino acid sequence of the blood coagulation factor and the DNA encoding a promotor specific to the expression in hematopoietic cells, and it is useful for the genetic treatment of hemophilia B or the like. The DNA structure is obtained by inserting an promotor which consists of the DNA encoding the amino acid sequence of a blood coagulation factor consisting of the cDNA encoding blood coagulation IX factor or the like, and the DNA encoding human platelet glycoprotein IIb(GPIIb) or the like, and which is specific to the expression in hematopoietic cells, into an appropriate expression vector.
