Recombinant HEK293T cells stably overexpress coronavirus SARS-CoV-2 spike protein on the surface. The surface expression of SARS-CoV-2 spike protein is validated by FACS analysis. This stable cell line product is designed for screening antibodies against SARS-CoV-2 spike protein, as well as for measuring binding affinity and stability of antibody based biologics that bind with spike protein. GenScript also offers spike protein expressing CHO-K1 stable cell line (Cat. No. M00803) for SARS-CoV-2 study.
