Methods for propagating viruses using MDCK-derived cell lines and such cell lines in suspension culture in protein-free medium

摘要

present invention relates to novel MDCK-derived cell line capable of suspension culture in protein-free medium, and to produce vaccines using the MDCK-derived cell line to a method of growing the virus. The new MDCK-derived cell lines, higher for various viruses, showed uniform productivity, whereas a change in the antigenicity of the virus is small, has a low tumorigenic potential, therefore, the production of virus used in the vaccine It may be useful to.FIELD 6
