Used in research to study signaling pathways related to cell growth, survival, and migration. Plays a role in cancer studies due to its involvement in tumor progression and metastasis. Employed in protein-protein interaction assays, such as binding studies with ligands or therapeutic antibodies. The Fc tag enables easy detection and purification, making it useful in immunoassays and flow cytometry. Supports development and testing of biologics targeting the c-Met pathway.
