Used in immunological research to study the role of MERTK in macrophage function and immune regulation. Employed in protein-protein interaction studies, particularly in signaling pathways related to phagocytosis and inflammation. Serves as a detection tool in assays such as ELISA, Western blot, and immunoprecipitation due to the His tag facilitating purification and recognition. Applied in cancer research to investigate MERTK's involvement in tumor immune evasion and as a potential target for immunotherapy. Also utilized in the development and validation of anti-MERTK therapeutic antibodies and small molecule inhibitors.
