Human DcR3/TNFRSF6B Antibody Summary

Species Reactivity

Human

Specificity

Detects human DcR3/TNFRSF6B in direct ELISAs and Western blots. In Western blots, no cross-reactivity with recombinant human (rh) Fas, rhOPG, rhTNF R2, rhTRAIL R1, rhTRAIL R2, rhTRAIL R3, or rhTRAIL R4 is observed.

Source

Monoclonal Mouse IgG₁ Clone # 229812

Purification

Protein A or G purified from hybridoma culture supernatant

Immunogen

Mouse myeloma cell line NS0-derived recombinant human DcR3/TNFRSF6B
Val24-His300
Accession # O95407

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Endotoxin Level

<0.10 EU per 1 μg of the antibody by the LAL method.

Applications

Recommended Concentration

Sample

Western Blot

1 µg/mL

Recombinant Human DcR3/TNFRSF6B Fc Chimera (Catalog # 142-DC)
under non-reducing conditions only

Neutralization

Measured by its ability to neutralize DcR3/TNFRSF6B-mediated inhibition of apoptosis in the Jurkat human acute T cell leukemia cell line. The Neutralization Dose (ND₅₀) is typically 0.1-0.4 µg/mL in the presence of 1 µg/mL Recombinant Human DcR3/TNFRSF6B Fc Chimera, 20 ng/mL Recombinant Human Fas Ligand/TNFSF6, and 10 µg/mL of a cross-linking antibody, Mouse polyHistidine Monoclonal Antibody.

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.

DcR3/TNFRSF6B Inhibition of Fas Ligand/TNFSF6-induced Apoptosis and Neutralization by Human DcR3/TNFRSF6B Antibody. In the presence of a cross-linking antibody, Mouse polyHistidine Monoclonal Antibody (10 µg/mL, Catalog # MAB050), Recombinant Human DcR3/TNFRSF6B Fc Chimera (Catalog # 142-DC) inhibits Recombinant Human Fas Ligand/TNFSF6 (Catalog # 126-FL) induced apoptosis in the Jurkat human acute T cell leukemia cell line in a dose-dependent manner (orange line). Under these conditions, inhibition of Recombinant Human Fas Ligand/TNFSF6 (20 ng/mL) activity elicited by Recombinant Human DcR3/TNFRSF6B Fc Chimera (1 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human DcR3/TNFRSF6B Monoclonal Antibody (Catalog # MAB2135). The ND₅₀ is typically 0.1-0.4 µg/mL.

Background: DcR3/TNFRSF6B

Human decoy receptor 3 (DcR3), also called TNFRSF6B, TR6 and M68, is a member of the TNF receptor superfamily. The cDNA of DcR3 encodes a 300 amino acid (aa) polypeptide with a putative 23 aa signal peptide. Like osteoprotegerin (OPG), DcR3 lacks a transmembrane sequence and is a secreted protein. DcR3 shares sequence identity with OPG (31%), TNFRII (29%) and Fas (17%). It was found to be expressed in a variety of different tissues and at high levels in many malignant tumors. Among TNF family members, DcR3 was shown to bind with Fas ligand (FasL) and LIGHT and inhibit FasL- and LIGHT-induced apoptosis. Thus, in addition to DcR1, DcR2 and OPG, DcR3 is another TNFR family molecule which modulates ligands that induce apoptosis. Overexpression of DcR3 might be a mechanism by which certain tumors escape immune-cytotoxic attack.
