TNFRSF9 (4-1BB/CD137) is a key costimulatory receptor in immuno-oncology whose engagement with its ligand TNFSF9 amplifies T-cell activation and antitumor immunity. This recombinant construct spans the extracellular ligand-binding domain (aa 24–186), expressed in mammalian cells with a C-terminal 10×His tag to preserve native glycosylation and conformational integrity critical for receptor-ligand interaction studies. Functional ELISA confirms robust binding to TNFSF9 with an EC50 of 1.011–2.429 ng/mL, supporting use in ligand-binding assays, competitive inhibition studies, blocking antibody screening, and therapeutic antibody epitope mapping relevant to immune checkpoint drug discovery. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the quality thresholds commonly required for SPR/BLI affinity characterization and cell-based functional assays in cancer immunology research.

Review: After receiving the product, we conducted ELISA experiments to verify the good binding activity between TNFRSF9 and the ligand TNFSF9, and the EC50 was 2.671-3.702 ng/mL, which can be used for subsequent immune and antibody screening experiments. Compared to other manufacturers, it has high activity, favorable prices, short delivery time, and high cost-effectiveness!
