Viral Vector Production in HEK Cells

Online Inquiry


HEK293, a human embryonic kidney cell line, has been widely used for the production of recombinant proteins and viral vectors, including adenoviral vectors. HEK293 cells have several advantages for viral vector production, such as high transfection efficiency, high cell growth rate, and the ability to support the replication of adenoviral vectors.

CD Biosynsis has extensive experience in viral vector production in HEK cells, utilizing our advanced technology and expertise to provide high-quality services for our clients.
