Detects human TRAIL R3/TNFRSF10C in direct ELISAs and Western blots. In direct ELISAs, approximately 20%‑40% cross-reactivity with recombinant human (rh) TRAIL R1 is observed and no cross-reactivity with rhTRAIL R2 or rhTRAIL R4 is observed.
Monoclonal Mouse IgG1 Clone # 90903
Protein A or G purified from ascites
Mouse myeloma cell line NS0-derived recombinant human TRAIL R3/TNFRSF10C Ala26-Ala221 Accession # O14798
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize TRAIL R3/TNFRSF10C-mediated inhibition of cytotoxicity in the L‑929 mouse fibroblast cell line. The Neutralization Dose (ND50) is typically 0.02-0.08 µg/mL in the presence of 10 ng/mL Recombinant Human TRAIL R3/TNFRSF10C Fc Chimera, 20 ng/mL of Recombinant Human TRAIL/TNFSF10, and 1 µg/mL actinomycin D.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
TRAIL R3/TNFRSF10C Inhibition of TRAIL/TNFSF10-induced Cytotoxicity and Neutralization by Human TRAIL R3/TNFRSF10C Antibody. In the presence of the metabolic inhibitor actinomycin D (1 µg/mL), Recombinant Human TRAIL R3/TNFRSF10C Fc Chimera (Catalog # 630-TR) inhibits Recombinant Human TRAIL/TNFSF10 (Catalog # 375-TEC) induced cytotoxicity in the L‑929 mouse fibroblast cell line in a dose-dependent manner (orange line). Under these conditions, inhibition of Recombinant Human TRAIL/TNFSF10 (20 ng/mL) activity elicited by Recombinant Human TRAIL R3/TNFRSF10C Fc Chimera (10 ng/mL) is neutralized (green line) by increasing concentrations of Human TRAIL R3/TNFRSF10C Monoclonal Antibody (Catalog # MAB630). The ND50 is typically 0.02-0.08 µg/mL.

Background: TRAIL R3/TNFRSF10C
TRAIL R3, also called TNFRSF10C, DcR1 (decoy receptor 1), LIT, and TRID, is a glycosylphosphatidylinositol-linked membrane protein which binds TRAIL (Apo2 Ligand) with high affinity (1, 2). TRAIL R3 contains a TRAIL-binding extracellular cysteine-rich domain but lacks an intracellular signaling domain. As a result, binding of TRAIL to TRAIL R3 does not trigger a pro-apoptotic signal. TRAIL R3 has been shown to protect cells bearing TRAIL R1 and/or TRAIL R2 from TRAIL-induced apoptosis.
