Abstract:
This invention discloses a production process for recombinant human endostatin adenovirus in order to optimize the procedure for small batch and mass industrialization. Exemplary process include steps of: (1) fermentation of eukaryotic cells (HEK293 cells) in the condition of 37° C. and 5% CO2; (2) adenovirus infection; (3) collection of diseased cells; (4) freezing and thawing; (5) concentration by ultrafiltration; and (6) preparation and packaging of recombinant human endostatin adenovirus. The process is controllable and easy to operate. The concentration of adenovirus titers can reach 1.0×1012−3.0×1012 vp/ml.
Abstract:
The invention generally relates to compositions of and methods for production of recombinant adenoviruses that carry therapeutic genes. More particularly, the invention relates to lyophilized recombinant adenoviruses injection and its related production procedures, including production procedures for the recombinant adenovirus vectors (or other viral vectors) that carry the genes of human endostatins.
Abstract:

Abstract:
An assay method for determining the effect of Product R on virus infection of Hela cells. The method comprising the following step: (1) dividing Hela cells into several groups, (2) treating one group with Product R prior to infecting the cells with a virus and treating another group with Product R after the cells being infected with the virus, and (3) determining the effects of Product R on virus infection by comparing the changes in the cell cycle, DNA fragmentation and p53 protein in cells undergone the different treatments in step (2).
