Product Specifications
Immunogen
TNF-alpha Antibody used to produce this IgG fraction antibody was prepared by repeated immunizations with recombinant human TNFa. (Uniprot: P01375)
Specificity
This antibody is primarily directed against mature 17,000 MW human TNFalpha and is useful in determining its presence in various assays. In general, this antibody also detects primate TNFalpha in the same formats using similar dilutions. The antibody does not recognize human TNFbeta (lymphotoxin). This IgG fraction antibody will recognize the cell-bound precursor of TNFalpha as a 26,000 protein in immunoblots, particularly in denatured samples. This antibody is also useful for neutralization of human and primate TNFalpha activity in bioassays. It does not neutralize the biological activity of lymphotoxin. For neutralization, it is recommended to incubate the sample with a 1:200 dilution of the antibody for at least 4 hours before being tested. A control of similarly diluted normal rabbit IgG is recommended.

Background: TNF-alpha
TNF-alpha is critical for normal immune response; however, dysregulation of TNF-alpha production can result in various pathologies (2,4,5). Excessive production of pro-inflammatory cytokines including interleukin 1 (IL-1), IL-6, and TNF-alpha has been implicated in an array of autoimmune diseases like rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis (2,4,5). Anti-TNF monoclonal antibodies, including Infliximab, and soluble TNFR have been approved for the treatment of autoimmune and TNF-mediated diseases (5). Additionally, data suggests that TNF inhibitors can be beneficial for treating patients experiencing immune-related adverse events associated with immune checkpoint inhibitor cancer treatment (6).
