huCD226-CHO-S is used in immunological research to study the function and signaling pathways of the CD226 receptor, which plays a key role in immune cell activation. It is particularly applied in assays involving natural killer (NK) cells and T cells to evaluate cell adhesion, cytotoxicity, and cytokine production. The molecule supports the development of therapeutic antibodies and checkpoint inhibitors by serving as a target antigen in binding and functional studies. It is also employed in protein-protein interaction experiments to identify ligands or inhibitors that modulate immune responses. Its use in CHO cell-based systems allows for consistent post-translational modifications relevant to human immune biology.
