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.

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 0.5-1.5 µg/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.

TNF RII/TNFRSF1B Inhibition of TNF‑ alpha -induced Cytotoxicity and Neutralization by Human TNF RII/TNFRSF1B Antibody.
Recombinant Human TNF RII/TNFRSF1B Fc Chimera (Catalog # 726-R2) inhibits Recombinant Human TNF‑ alpha (Catalog # 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‑ alpha (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 0.5-1.5 µg/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
