Description
Recombinant CHO-K1 cells stably overexpress human neonatal Fc receptor (FcRn) and beta-2 microglobulin (B2M). The existence of B2M enables the stable expression of FcRn. The surface expression of FcRn is validated by FACS analysis. This stable cell line product is designed for measuring binding affinity and stability of Fc region of antibodies, Fc fusion proteins, and antibody based biologics that binds with FcRn during biologics research and development.
