Figure 1: FACS analysis of cell surface expression of mouse CTLA4 on CHO-K1/mouse CTLA4 cells. The CHO-K1/mouse CTLA4 cells (blue) and the negative control CHO-K1 cells (red) were probed using PE anti-mouse CD152 (Cat. No. 106305, Biolegend).

CHO-K1/mouse CTLA4 Stable Cell Line

Recombinant CHO-K1 cells stably overexpress Mus musculus cytotoxic T-lymphocyte-associated protein 4 (CTLA4) on the surface. The surface expression of mouse CTLA4 is validated by FACS analysis. This cell line is designed for cell-based binding for screening antibodies binding with mouse CTLA4 and for evaluating target binding affinity.

Background

CTLA4 or CTLA-4 (cytotoxic T-lymphocyte-associated protein 4), also known as CD152 (cluster of differentiation 152), is a protein receptor that, functioning as an immune checkpoint, downregulates immune responses. CTLA4 is constitutively expressed in Tregs but only upregulated in conventional T cells after activation. It acts as an "off" switch when bound to CD80 or CD86 on the surface of antigen-presenting cells.
