Used in research and development of targeted cancer therapies, particularly in studies involving fibroblast growth factor receptor signaling pathways. Plays a role in assays to evaluate receptor activation, ligand binding, and inhibition by potential therapeutic agents. Commonly employed in cell-based systems for screening monoclonal antibodies or small molecules that modulate FGFR2b activity. Supports the study of tissue repair, cell proliferation, and differentiation in disease models such as lung, gastric, and breast cancers. Also utilized in the validation of diagnostic tools and biomarker discovery related to FGFR2 isoform expression.
