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 0.2-0.8 µg/mL in the presence of 1 ng/mL Recombinant Rhesus Macaque 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.
Cytotoxicity Induced by TNF‑ alpha and Neutralization by Rhesus Macaque TNF‑ alpha Antibody. Recombinant Rhesus Macaque TNF‑ alpha (Catalog # 1070-RM) induces cytotoxicity in the the L‑929 mouse fibroblast cell line in a dose-dependent manner (orange line), as measured by crystal violet staining. Cytotoxicity elicited by Recombinant Rhesus Macaque TNF‑ alpha (1 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Rhesus Macaque TNF‑ alpha Monoclonal Antibody (Catalog # MAB10701). The ND50 is typically 0.2‑0.8 µg/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL).

Tumor necrosis factor alpha (TNF-alpha ), also known as cachectin and TNFSF2, is the prototypic ligand of the TNF superfamily. It is a pleiotropic molecule that plays a central role in inflammation, apoptosis, and immune system development. TNF-alpha is produced by a wide variety of immune and epithelial cell types (1, 2). Rhesus TNF-alpha consisits of a 35 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 177 aa extracellular domain (ECD) (3). Within the ECD, rhesus TNF-alpha shares 97% aa sequence identity with human and 71%‑92% with bovine, canine, cotton rat, equine, feline, mouse, porcine, and rat TNF-alpha. The 26 kDa type 2 transmembrane protein is assembled intracellularly to form a noncovalently linked homotrimer (4). Ligation of this complex induces reverse signaling that promotes lymphocyte costimulation but diminishes monocyte responsiveness (5). Cleavage of membrane bound TNF-alpha by TACE/ADAM17 releases a 55 kDa soluble trimeric form of TNF-alpha (6, 7). TNF-alpha trimers bind the ubiquitous TNF RI and the hematopoietic cell-restricted TNF RII, both of which are also expressed as homotrimers (1, 8). TNF-alpha regulates lymphoid tissue development through control of apoptosis (2). It also promotes inflammatory responses by inducing the activation of vascular endothelial cells and macrophages (2). TNF-alpha is a key cytokine in the development of several inflammatory disorders (9). It contributes to the development of type 2 diabetes through its effects on insulin resistance and fatty acid metabolism (10, 11).
