Scientific Data Images for Rhesus Macaque TNF‑ alpha Antibody

Cytotoxicity Induced by TNF‑ alpha and Neutralization by Rhesus Macaque TNF‑ alpha Antibody.

Recombinant Rhesus Macaque TNF-a (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-a (1 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Rhesus Macaque TNF-a 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).

Applications for Rhesus Macaque TNF‑ alpha Antibody

Application

Recommended Usage

Neutralization

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.

Background: TNF-alpha

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).
