    摘要: The present invention provides for a process for preparing a recombinant human thrombin. A process for preparing a recombinant human thrombin which comprises: (1) obtaining a transfectant cell producing a human prothrombin by introducing an expression vector, wherein a gene fragment coding for a human prothrombin gene is incorporated, into an animal cell; (2) purifying a human prothrombin from the culture of the transfectant cell above by an anion exchanger; (3) converting the purified human prothrombin into a human thrombin by subjecting said human prothrombin to the action of ecarin; and (4) purifying the human thrombin from the solution after treatment with ecarin by an affinity method using benzamidine and a cation exchanger, and human thrombin obtained by said process, and a CHO cell that produces human prothrombin.

    摘要: A method for producing influenza virus on large scale is provided. A method for propagating influenza virus which comprises, after removing or decreasing a trypsin inhibitor secreted into culture of MDCK cells (cell line derived from dog kidney) by washing with a culture medium or a buffer, inoculating influenza virus into said cells and culturing said influenza virus-inoculated cells in a culture medium supplemented with trypsin.

    摘要: A human Activated Protein C preparation with a high specific activity of 3500 U/mg or more and substantially free from thrombin or other proteases which can convert Protein C into Activated Protein C is provided. A process for preparing this human Activated Protein C, which involves, contacting a solution of human Activated Protein C, after activation of Protein C with thrombin or other activating protease, with a cation exchanger to allow for adsorption of both thrombin or another activating protease and Activated Protein C to the cation exchanger followed by elution of the human Activated Protein C alone.
