Used in research and development of targeted cancer therapies, particularly in studies involving fibroblast growth factor receptor signaling pathways. Plays a role in cell-based assays to evaluate receptor-ligand interactions and screen potential inhibitors. Supports the production of recombinant proteins in CHO (Chinese Hamster Ovary) cell systems, enabling high-yield expression and proper post-translational modifications. Applied in preclinical studies to understand tumor growth mechanisms in cancers where FGFR2 isoforms are overexpressed, such as gastric, breast, and lung carcinomas. Also utilized in the development of monoclonal antibodies and biologics that modulate FGFR2 activity.
