TNFRSF1B (TNFR2) plays a critical role in TNF-α signaling within the tumor microenvironment, making it a key target for immunotherapy and cancer biology research. This recombinant human TNFRSF1B extracellular domain (aa 23–257) demonstrates confirmed ligand-binding activity, with an ED50 of 0.212 µg/ml against immobilized TNF-α in functional ELISA, providing a suitable basis for receptor-ligand interaction assays, competitive inhibition studies, and blocking antibody screening. Mammalian cell expression ensures native glycosylation and proper disulfide bond formation across the cysteine-rich domains, preserving conformational integrity essential for SPR/BLI affinity characterization, therapeutic antibody epitope mapping, and small-molecule inhibitor screening. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/µg satisfies the criteria typical for sensitive binding assays where the C-terminal 6×His tag enables oriented immobilization on Ni-NTA surfaces.
