Used in immunological research to study the AXL receptor's role in immune modulation and viral entry mechanisms. Facilitates development of therapeutic antibodies and inhibitors targeting AXL signaling in inflammatory diseases and cancer. Employed in binding assays and structural studies due to its high purity and His-tag for easy detection and immobilization. Supports vaccine research, particularly in non-human primate models, by enabling analysis of receptor-ligand interactions in relevant biological systems.
