Immunogen
E. coli-derived recombinant canine TNF-alpha
Val77-Leu233
Accession # P51742
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.

Use in combination with:

Detection Reagent: Canine TNF‑ alpha Biotinylated Antibody (Catalog # BAF1507)

Standard: Recombinant Canine TNF-alpha Protein (Catalog # 1507-CT)

Neutralization
Measured by its ability to neutralize TNF‑ alpha -induced cytotoxicity in the L‑929 mouse fibroblast cell line. The Neutralization Dose (ND50) is typically 1.25-5.0 µg/mL in the presence of 10 ng/mL Recombinant Canine 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 Canine TNF‑ alpha Antibody. Recombinant Canine TNF-a (Catalog # 1507-CT) induces cytotoxicity in the the L-929 mouse fibroblast cell line in a dose-dependent manner (orange line). Cytotoxicity elicited by Recombinant Canine TNF-a (10 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Canine TNF-a Monoclonal Antibody (Catalog # MAB1507). The ND50 is typically 1.25-5.0 µg/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL).

TNF‑ alpha in Canine PBMCs. TNF-a was detected in immersion fixed canine peripheral blood mononuclear cells (PBMCs) untreated or treated with calcium ionomycin and PMA using Mouse Anti-Canine TNF-a Monoclonal Antibody (Catalog # MAB1507) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell secretion. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background: TNF-alpha

Tumor necrosis factor alpha (TNF-alpha ), also known as cachectin, 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). Canine 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, canine TNF-alpha shares
84‑94% aa sequence identity with equine, feline, human, porcine, and rhesus and 69-77% with bovine, cotton rat, mouse, and rat with 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 co-stimulation 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).
