Used in research and development of targeted cancer therapies, particularly in studies involving fibroblast growth factor receptor signaling pathways. Plays a role in the production of monoclonal antibodies and antibody-drug conjugates by serving as a hapten or immunogen to generate specific immune responses. Commonly applied in immunoassay development, including ELISA and flow cytometry, to detect and quantify anti-FGFR2 antibodies. Also utilized in quality control processes during biopharmaceutical manufacturing to ensure antibody specificity and binding affinity. Its structure supports conjugation to carrier proteins for enhanced immunogenicity in preclinical studies.
