Recombinant Cynomolgus / Rhesus Macaque B7-H6 (NCR3LG1), Fc Tag, is used in immunological research to study the interaction between B7-H6 and its receptor NKp30 (NCR3) in non-human primate models. This Fc-tagged protein facilitates assays involving immune cell activation, particularly natural killer (NK) cell function. The Fc tag allows for easy detection and purification, and supports use in binding studies, ELISA, flow cytometry, and protein-protein interaction experiments. It is also employed in therapeutic development to evaluate immune checkpoint pathways and design biologics that modulate NK cell responses in cancer and infectious diseases, with relevance to cross-species studies.
