Product Description |
Recombinant CHO-K1 cells stably overexpress human immunoglobulin gamma Fc region receptor II-b (FcγRIIb/CD32B 232Ile) on the surface. The surface expression of CD32B 232Ile is validated by FACS analysis. This stable cell line product is designed for measuring binding affinity and stability of Fc region of antibodies and Fc fusion proteins, or antibody based biologics binding with CD32B 232Ile. GenScript also offers CD32B 232Thr stable cell line (Cat. No. M00600) for FcγRIIb polymorphism study. |

Figure 1: FACS analysis of cell surface expression of CD32B 232Ile on CHO-K1 cells.
CHO-K1/CD32B 232Ile cells (blue) and negative control CHO-K1 cells (red) were probed using APC Mouse Anti-Human CD32 antibody (Cat. No. 303208, Biolegend).

Figure 2: FACS analysis of cell surface expression of CD32B 232Ile on CHO-K1 cells from different passages.
CHO-K1/CD32B 232Ile cells and negative control CHO-K1 cells were probed using APC Mouse Anti-Human CD32 antibody (Cat. No. 559769, BD Biosciences). P17, P23, P28, and P33 represent cell passage numbers.
