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 where 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. Genetically engineered genes for the polypeptides are described and expressed as a fusion protein using the pJC264 expression vector in E. coli . Synthetic polypeptides and methods of synthesis are also described.
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.
摘要:
Certain Factor XIIIa inhibitor compounds have been discovered which have been found to be useful in the lysis of blood clots and thus adaptable for administration in thrombolytic therapy either alone or together with plasminogen activator.
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:
Peptides comprising the tripeptide sequence of arginine-tyrosine-aspartic acid, linked from amino- to carboxy-terminus, are inhibitors of fibrinogen binding, platelet aggregation, glycoprotein IIb-IIIa binding and related aberrant and normal physiological conditions.

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.
