Description
TNFRSF9 (4-1BB) is a key costimulatory receptor in immuno-oncology, and this recombinant extracellular domain (aa 24–186) provides a functionally validated tool for dissecting its interaction with 4-1BB ligand. Produced in mammalian cells with a C-terminal Fc tag, the protein preserves native glycosylation and disulfide-mediated folding critical for accurate ligand-binding studies. Functional ELISA confirms robust activity, with an ED50 of 16.8 ng/mL against immobilized 4-1BBL-His, supporting use in receptor-ligand interaction assays, competitive blocking antibody screening, therapeutic antibody epitope mapping, and affinity characterization by SPR or BLI. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the quality thresholds commonly required for immune checkpoint drug discovery workflows, including small-molecule and biologic inhibitor screening.
