Used in research and development of targeted cancer therapies, particularly in studies involving tumor cell proliferation, survival, and metastasis. Plays a role in immunoassay development and as a binding partner in protein-protein interaction studies due to its fusion with the Fc tag, enabling easy detection and purification. Supports the development of monoclonal antibodies and therapeutic agents aimed at modulating AXL signaling in diseases such as leukemia, breast cancer, and lung cancer. Also utilized in diagnostic applications to detect AXL expression levels in patient samples.
