    摘要: Embodiments of the invention include E1 expressing cell lines that can be used in a variety of methods for production of an E1 defective adenovirus. In certain aspects a cell of the invention can be adapted to various culture conditions, e.g., suspension culture in serum free medium. In a further aspect, the cell lines allow isolation and subculture of E1-deleted recombinant adenoviruses in an environment free of replication competent adenovirus (RCA).

    摘要: The present invention addresses the need to improve the yield of adenovirus when grown in cell culture systems. In particular, it has been demonstrated that for adenovirus, the use of infection temperatures lower than 37° C. in a cell culture system results in improved yields of adenovirus. In addition, it has been demonstrated that when host cells are grow in a bioreactor, initiating adenovirus infection by diluting the host cells with fresh media and adenovirus results in improved yield of adenovirus. Methods of adenoviral production and purification using infection temperatures less than 37° C. are disclosed. Methods of adenoviral production and purification wherein the host cells are grown in a bioreactor and adenovirus infection is initiated by diluting the host cells with fresh media and adenovirus are also disclosed.
