Description
CD25, the high-affinity alpha subunit of the IL-2 receptor, plays a central role in T cell activation and is a validated target in cancer immunotherapy and autoimmune disease research. This mammalian-expressed construct spanning residues 22–236 captures the complete extracellular ligand-binding domain and demonstrates quantified binding to mouse IL-2 with an EC50 of 95.00–116.2 ng/mL in functional ELISA, providing a defined benchmark for ligand-receptor interaction studies and competitive inhibition assays. The mammalian expression system ensures native glycosylation and disulfide bond formation critical for conformational integrity in surface plasmon resonance, biolayer interferometry, and therapeutic antibody epitope mapping experiments. With purity exceeding 95% by SDS-PAGE and endotoxin levels below 1.0 EU/μg, this protein meets the quality thresholds commonly required for blocking antibody screening, small-molecule inhibitor discovery, and affinity characterization workflows targeting the IL-2/IL-2R axis in immuno-oncology research.
