Recombinant Human TNF RI/TNFRSF1A (Catalog # 636-R1) under non-reducing conditions only
Human TNF RI/TNFRSF1A Biotinylated Antibody (Catalog # BAF225)
Recombinant Human sTNF RI/TNFRSF1A Protein (Catalog # 636-R1)
Measured by its ability to neutralize TNF RI/TNFRSF1A-mediated inhibition of cytotoxicity in the L‑929 mouse fibroblast cell line. The Neutralization Dose (ND50) is typically 1-6 µg/mL in the presence of 0.3 μg/mL Recombinant Human TNF RI/TNFRSF1A, 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 RI/TNFRSF1A Inhibition of TNF‑ alpha -induced Cytotoxicity and Neutralization by Human TNF RI/TNFRSF1A Antibody.
Recombinant Human TNF RI/TNFRSF1A (Catalog # 636‑R1) 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). Inhibition of Recombinant Human TNF‑ alpha (0.25 ng/mL) activity elicited by Recombinant Human TNF RI/TNFRSF1A (0.3 μg/mL) is neutralized (green line) by increasing concentrations of Human TNF RI/TNFRSF1A Monoclonal Antibody (Catalog # MAB625). The ND50 is typically 1-6 µg/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL).

Background: TNF RI/TNFRSF1A
TNF RI occurs both in membrane bound and soluble forms and functions as a receptor for TNF-alpha and TNF-beta. In the superfamily nomenclature, it is designated TNFRSF1A.
