    摘要: A platelet aggregation inhibiting polypeptide having the following amino acid sequence:
    X-Cys-R-R-R-Arg-Gly-Asp-R-R-R-R-R-Cys-Y
    wherein X is H or at least one amino acid; Y is OH or at least one amino acid; and each R, either the same or different, is any amino acid. Polypeptides having this sequence are potent inhibitors of fibrinogen binding to receptors expressed on the glycoprotein IIb/IIIa complex in the membrane of platelets, and are therefore potent inhibitors of fibrinogen-induced human platelet aggregation. They are useful in inhibition of platelet aggregation formation.

    摘要: A process for culturing cells in monolayer which comprises :

    a. seeding a culture vessel with a cell stock in a minimal or rich medium and allowing the cells to plant for about 24-72 hours;
    b. removing the medium from the culture of step a. and replacing with fresh, rich medium, supplemented with an opitimized concentration of lipids and optionally also including a serum supplement;
    c. growing the culture of cells in rich medium supplemented with lipid;
    d . optionally replacing the medium of Step c. with fresh medium containing no lipid supplement, after about 24-72 hours growth.

    摘要: A live, attenuated varicella zoster virus vaccine is produced with enhanced yield of VZV. The new process makes mass production of a live VZV vaccine more practical. In addition, optimized monolayer cell culture conditions provide a process for maximizing monolayer cell density which is useful for enhancing viral vaccine production. According to this process, cell densities approaching 500,000 cells/cm² are routinely achieved in conventional culture vessels.
