Human TNF RII/TNFRSF1B Antibody Summary

Species Reactivity
Detects human TNF RII in ELISAs and Western blots. In ELISAs, no cross-reactivity or interference was observed with recombinant human (rh) TNF RI, recombinant mouse (rm) TNF RI, rmTNF RII, rmTNF‑ alpha, rhTNF‑ alpha, or rhTNF‑ beta. In Western blots, this antibody does not
cross‑react with rhTNF RI, rmTNF RI, or rmTNF RII.
Monoclonal Mouse IgG1 Clone # 22210
Protein A or G purified from hybridoma culture supernatant
E. coli-derived recombinant human TNF RII/TNFRSF1B
Accession # P20333
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.

Recombinant Human TNF RII/TNFRSF1B Fc Chimera (Catalog # 726-R2)
under non-reducing conditions only

Human TNF RII/TNFRSF1B Sandwich Immunoassay

Recommended Concentration
ELISA Capture (Matched Antibody Pair)
2-8 µg/mL 

Use in combination with:

Detection Reagent: Human TNF RII/TNFRSF1B Biotinylated Antibody (Catalog # BAF726)

Standard: Recombinant Human TNF RII/TNFRSF1B (aa 24-206) Protein (Catalog # 1089-R2)

Measured by its ability to neutralize TNF RII/TNFRSF1B-mediated inhibition of cytotoxicity in the L‑929 mouse fibroblast cell line. The Neutralization Dose (ND50) is typically 30.0-300 ng/mL in the presence of 0.3 µg/mL Recombinant Human TNF RII/TNFRSF1B Fc Chimera, 0.25 ng/mL Recombinant Human TNF‑ alpha, 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.

TNF RII/TNFRSF1B Inhibition of TNF‑ alpha -induced Cytotoxicity and Neutralization by Human TNF RII/TNFRSF1B Antibody. Recombinant Human TNF RII/TNFRSF1B Fc Chimera (726-R2) inhibits Recombinant Human TNF-a (210-TA) induced cytotoxicity in the L-929 mouse fibroblast cell line in a dose-dependent manner (orange line), as measured by crystal violet staining. Inhibition of Recombinant Human TNF-a (0.25 ng/mL) activity elicited by Recombinant Human TNF RII/TNFRSF1B Fc Chimera (0.3 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human TNF RII/TNFRSF1B Monoclonal Antibody (Catalog # MAB726). The ND50 is typically 30.0-300 ng/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL).

Background: TNF RII/TNFRSF1B

TNF RII, also known as p75 or p80 TNF R, is a prototypic member of the TNF receptor superfamily and has been designated TNFRSF1B. It binds TNF with high affinity and is expressed primarily in cells of the immune system.
