Sheehan, K. et al. (1995) J. Exp. Med. 181:607.
Measured by its ability to neutralize TNF‑ alpha -induced cytotoxicity in the L‑929 mouse fibroblast cell line. Matthews, N. and M. L. Neale (1987) in Lymphokines and Interferons, A Practical Approach. Clemens, M. J. et al. (eds): IRL Press. 221. The Neutralization Dose (ND50) is typically 5-20 µg/mL in the presence of 0.1 ng/mL Recombinant Mouse TNF‑ alpha and 1 µg/mL actinomycin D.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Cytotoxicity Induced by TNF‑ alpha and Neutralization by Mouse TNF RI/TNFRSF1A Antibody.
Recombinant Mouse TNF‑ alpha (Catalog # 410-MT) induces cytotoxicity in the the L‑929 mouse fibroblast cell line in a dose-dependent manner (orange line). Cytotoxicity elicited by Recombinant Mouse TNF‑ alpha (0.1 ng/mL) is neutralized (green line) by increasing concentrations of Hamster Anti-Mouse TNF RI/TNFRSF1A Monoclonal Antibody (Catalog # MAB430). The ND50 is typically 5-20 µg/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL).

Background: TNF RI/TNFRSF1A
TNF receptor 1 (TNF RI; also called TNF R-p55/p60 and TNFRSF1A) is a type I transmembrane protein member of the TNF receptor superfamily, designated TNFRSF1A (1, 2). Both TNF RI and TNF RII (TNFRSF1B) are widely expressed and contain four TNF-alpha trimer-binding cysteine-rich domains (CRD) in their extracellular domains (ECD). However, TNF RI is thought to mediate most of the cellular effects of TNF-alpha (3). It is essential for proper development of lymph node germinal centers and Peyer’s patches, and for combating intracellular pathogens such as Listeria (1‑3). TNF RI is also a receptor for TNF-beta /TNFSF1B (lymphotoxin-alpha ) (4). TNF RI is present on the cell surface as a trimer of 55 kDa subunits (4, 5). TNF-alpha induces sequestering of TNF RI in lipid rafts, where it activates NF kappa B and is cleaved by ADAM-17/TACE (9, 10). Release of the 28 - 34 kDa TNF RI ECD also occurs constitutively and in response to products of pathogens such as LPS, CpG DNA or S. aureus protein A (1, 6‑8). Full-length TNF RI may also be released in exosome-like vesicles (11). Release helps to resolve inflammatory reactions, since it down-regulates cell surface TNF RI and provides soluble TNF RI to bind TNF-alpha (6, 12, 13). Exclusion from lipid rafts causes endocytosis of TNF RI complexes and induces apoptosis (1). Mouse TNF RI is a 454 amino acid (aa) protein that contains a 21 aa signal sequence, a 191 aa ECD with a PLAD domain (5) that mediates constitutive trimer formation, followed by the four CRD, a 23 aa transmembrane domain, and a 219 aa cytoplasmic sequence that contains a neutral sphingomyelinase activation domain and a death domain (15). The ECD of mouse TNF RI shows 67%, 70%, 64%, 70% and 88% aa identity with canine, feline, porcine, human, and rat TNF RI, respectively; it shows 23% aa identity with the ECD of TNF RII.
