CHO-K1/ICOS Stable Cell Line

Recombinant CHO-K1 cells stably overexpress Homo sapiens inducible T cell costimulator (ICOS) on the surface. The surface expression of ICOS is validated by FACS analysis. This cell line is recommended for cell-based binding assay to screen antibodies against ICOS or to measure binding affinity between ICOS and anti-ICOS antibodies.
