Epithelial cell adhesion molecule plays a central role in homotypic cell–cell adhesion and has emerged as a critical biomarker and therapeutic target in epithelial cancers, making functional protein reagents essential for antibody development and tumor biology studies. This mammalian-expressed construct spanning residues 24–265 demonstrates robust binding activity with an EC50 of 1.098–1.401 ng/mL against a recombinant anti-EPCAM antibody in functional ELISA, and surface plasmon resonance analysis confirms high-affinity interaction with a binding constant of 0.742 nM. These quantitative binding metrics indicate that the protein retains native epitope presentation, providing a suitable basis for antibody validation, epitope mapping, and screening campaigns targeting EPCAM-expressing tumor cells. With purity exceeding 95% by SDS-PAGE and endotoxin levels below 1.0 EU/μg, the preparation meets the quality thresholds commonly required for cell-based adhesion assays and tumor metastasis research where low endotoxin is critical for preserving physiological cell behavior.
