Latest Patents

Haiyan Cui holds a patent for a cell strain designed to reduce the production of replication competent adenovirus. The patent, titled "Cell strain for reducing production of replication competent adenovirus, and construction method and use thereof," describes the HEK293.CS cell strain. This cell line is engineered by knocking out a gene fragment homologous to the Ad5 adenovirus E1 gene in HEK293 cells. The construction method involves replacing the gene fragment with a non-homologous sequence that stabilizes the expression of the E1 gene. Compared to the unmodified HEK293 cell strain, HEK293.CS maintains its growth and virus production capabilities while preventing the production of detectable replication competent adenovirus (RCA). This innovation is particularly useful for the mass culture of recombinant human type 5 adenovirus, thereby reducing the risk of RCA production in drug manufacturing processes, such as vaccines and antibodies.
