Used in immunological research to study melanocyte differentiation and immune responses in non-human primates. Serves as a critical reagent in developing and testing monoclonal antibodies, particularly in immuno-oncology and vaccine development. The Fc tag enables easy detection and purification, making it valuable in binding assays and protein-protein interaction studies. Commonly used in flow cytometry, ELISA, and Western blot applications to evaluate immune cell activation and antigen recognition. Supports preclinical studies due to its relevance in translational research models.
