Activity
Measured by its binding ability in a functional ELISA. Immobilized Human FGFR2 at 2 μg/ml can bind Anti-FGFR2 recombinant antibody (CSB-RA008645MA2HU). The EC50 is 2.051-2.322 ng/mL.
Description
FGFR2 dysregulation drives oncogenesis in gastric, breast, and endometrial cancers, making validated extracellular domain constructs essential tools for therapeutic antibody development and small-molecule inhibitor screening. This mammalian-expressed construct spanning residues 22–377 captures the complete ligand-binding region and demonstrates quantifiable antibody-binding activity with an EC50 of 2.051–2.322 ng/mL in functional ELISA, providing a reliable basis for competitive inhibition assays, blocking antibody screening, and epitope mapping studies. The measured affinity supports its use as a positive control in SPR and BLI experiments characterizing anti-FGFR2 therapeutic candidates. Purity exceeding 95% by SDS-PAGE and endotoxin levels below 1.0 EU/μg align with standards expected in antibody validation workflows and high-throughput drug discovery campaigns targeting receptor tyrosine kinase pathways.
