Used in immunological research to study cell adhesion mechanisms and immune responses in non-human primates. Serves as a critical reagent in the development and testing of monoclonal antibodies targeting Nectin-4, particularly in oncology and infectious disease research. Its His Tag facilitates easy purification and detection in assays, making it valuable for protein-protein interaction studies and vaccine development. Commonly employed in preclinical studies due to the close genetic similarity between cynomolgus/rhesus macaques and humans.
