Porcine TNF-alpha Antibody Summary

Species Reactivity

Porcine

Specificity

Detects porcine TNF-alpha in direct ELISAs and Western blots. In direct ELISAs, approximately 13% cross-reactivity with recombinant human (rh) TNF-alpha is observed and no cross-reactivity with recombinant mouse TNF-alpha, recombinant rat TNF-alpha, rhTNF-beta, rhAPRIL, rhFas Ligand, rhGITR Ligand, rhLIGHT, rhTrance, and rhVEGF is observed.

Source

Monoclonal Mouse IgG₁ Clone # 103314

Purification

Protein A or G purified from ascites

Immunogen

E. coli-derived recombinant porcine TNF-alpha
Arg78-Leu232
Accession # P23563

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.

Neutralization

Measured by its ability to neutralize TNF‑ alpha -induced cytotoxicity in the PK‑15 porcine kidney epithelial 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; Bertoni et al. (1993) J. Immunol. Meth. 160:267. The Neutralization Dose (ND₅₀) is typically 0.015-0.06 µg/mL in the presence of 0.05 ng/mL Recombinant Porcine 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 Porcine TNF‑ alpha Antibody. Recombinant Porcine TNF-a (Catalog # 690-PT) induces cytotoxicity in the the PK-15 porcine kidney epithelial cell line in a dose-dependent manner (orange line), as measured by crystal violet staining. Cytotoxicity elicited by Recombinant Porcine TNF-a (0.05 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Porcine TNF-a Monoclonal Antibody (Catalog # MAB6901). The ND₅₀ is typically 0.015-0.06 µg/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL).

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). Porcine TNF-alpha consisits of a 35 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 176 aa extracellular domain (ECD) (3). Within the ECD, porcine TNF-alpha shares 69%‑86% aa sequence identity with bovine, canine, cotton rat, equine, feline, human, mouse, rat, and rhesus 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).
