Used in research and development for studying melanin synthesis and melanosome formation due to its role in the structural matrix of melanosomes. Serves as a detection target in immunoassays and flow cytometry for identifying melanocyte-lineage cells. Applied in protein-protein interaction studies, particularly in investigating binding partners involved in pigmentation pathways. Utilized in the development of monoclonal antibodies for diagnostic tools and potential immunotherapies targeting melanoma and other pigmentation-related disorders. The Fc tag enables easy purification and detection using anti-Fc secondary reagents, enhancing its utility in laboratory settings.
