HEK FS_2 liquid, 1000 mL PET bottle

Unique on the market ! Ideal boost for production of viral vectors, virus for Gene Therapy and Vaccines.

HEK FS_2 is a chemically defined, animal component-free cell culture feed supplement. It is developed for the use as feeding solution in combination with HEK293 cell culture media, such as HEK GM for recombinant protein production or HEK ViP NX for viral vector production, making it the perfect booster for your gene therapy applications. The feed supplement contains highly concentrated nutrients to increase the productivity of HEK and other human cells. It does not contain lipids, hydrolysates, or growth factors. It supports superior production of recombinant proteins and antibodies in suspension culture by maintaining and extending the production capability of HEK cultures.
