CHO-K1/PD-L1 Stable Cell Line

Figure 1: FACS analysis of cell surface expression of PD-L1 on CHO-K1 cells. The CHO-K1/PD-L1 cells (red) and the negative control CHO-K1 cells (green) were probed using Anti-Human PD-L1 (GenScript) and Alexa Fluor™ 488 goat anti-human IgG (H+L) (Cat. No. A11013, Invitrogen).

CHO-K1/PD-L1 Stable Cell Line

Recombinant CHO-K1 cells stably overexpress human programmed cell death 1 ligand 1 (PD-L1) on the surface. The surface expression of PD-L1 is validated by FACS analysis. This cell line is recommended for cell-based binding assay to screen antibodies against PD-L1 or to measure binding affinity between PD-L1 and anti-PD-L1 antibodies.

Background Programmed death-ligand 1 (PD-L1) also known as cluster of differentiation 274 (CD274) or B7 homolog 1 (B7-H1) is a protein that in humans is encoded by the CD274 gene. The formation of PD-1 receptor/PD-L1 or B7.1 receptor/PD-L1 ligand complex transmits an inhibitory signal which reduces the proliferation of these CD8+ T cells at the lymph nodes and supplementary to that PD-1 is also able to control the accumulation of foreign antigen specific T cells in the lymph nodes through apoptosis which is further mediated by a lower regulation of the gene Bcl-2
