    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 invention relates to a process for preparing purified albumin from a human or animal physiological solution, such as a plasma or a plasma fraction. The process includes a process of delipidation using an anionic detergent and two chromatographic separation stages using ion-exchange resin. By applying the process according to the invention, it is possible to obtain an albumin solution of great purity, that is stable and suitable for therapeutic use.
