    摘要: Process for preparing a human thrombin concentrate from the PPSB fraction of plasma that does not involve any addition of factors of animal origin to induce activation of the prothrombin to produce thrombin, and which includes a viral inactivation step using solvent-detergent and purification by cation exchange chromatography. The choice of a protective medium ensures the high specific activity of the final product. The thrombin concentrate obtained using this process is intended for therapeutic use, either alone, to serve as a local hemostatic agent, or in combination with a fibrinogen concentrate to form biological glue.

    摘要: The present invention relates to a method for preparing a high purity Factor IX concentrate. The starting material for the process is the supernatant fraction of a cryoprecipitated human plasma. A pre-purification step is performed by DEAE-Sephadex chromatography. The resulting Factor IX fraction has a specific activity of at least 0.5 IU/mg protein. The purification method of the invention comprises two successive chromatography separations. First, ion-exchange chromatography on DEAE-sepharose is conducted so that the Factor IX is eluted when the ionic force of the buffer is increased to 0.34-0.38M sodium chloride. Then, affinity chromatography is conducted on heparin-sepharose. The elution buffer is a citrate buffer at a pH of 7.4 adjusted with 0.45M sodium chloride and supplemented with arginine as a stabilizer for Factor IX activity. Lysine is added as a stabilizer before freeze-drying of the purified Factor IX.
