TNFRSF4 (OX40) functions as a costimulatory receptor on activated T cells, making it a target of interest in cancer immunotherapy for enhancing antitumor immune responses. This mammalian-expressed construct spanning residues 29–216 captures the complete extracellular ligand-binding domain and demonstrates quantified binding activity with an EC50 of 4.882–5.863 ng/mL against an anti-TNFRSF4 antibody in functional ELISA, providing a validated basis for therapeutic antibody epitope mapping, competitive inhibition screening, and blocking antibody development. The confirmed receptor-antibody interaction supports its use as a positive control in ligand-binding assays and enables affinity characterization by surface plasmon resonance or biolayer interferometry when evaluating OX40-targeted biologics. Mammalian expression preserves native glycosylation and disulfide bonding critical for proper folding of this TNFR superfamily member, while purity exceeding 90% and endotoxin levels below 1.0 EU/μg satisfy the quality criteria typical for quantitative binding studies and small-molecule inhibitor screening in immune checkpoint research.
