Figure 1: FACS analysis of cell surface expression of VISTA on CHO-K1/VISTA cells. The CHO-K1/VISTA cells (red) and the negative control CHO-K1 cells (green and blue) were probed using PE-human VISTA (Cat. No. FAB71261P, R&D).

CHO-K1/VISTA Stable Cell Line

Recombinant CHO-K1 cells stably overexpress V-domain Ig suppressor of T cell activation (VISTA) on the cell surface. The surface expression of VISTA is validated by FACS analysis. This cell line is designed for cell-based binding for screening antibodies binding with VISTA and evaluating target binding affinity.

Background

V-domain Ig suppressor of T cell activation (VISTA) is a potent negative regulator of T-cell function that is expressed on hematopoietic cells. VISTA levels are heightened within the tumor microenvironment, in which its blockade can enhance antitumor immune responses in mice. In humans, blockade of the related programmed cell death 1 (PD-1) pathway has shown great potential in clinical immunotherapy trials. Here, we report the structure of human VISTA and examine its function in lymphocyte negative regulation in cancer.
