Scientific Data Images for TNF-alpha Antibody (CDP 571 (Humicade)) - Azide and BSA Free

Western Blot: TNF-alpha Antibody (CDP 571 (Humicade))Azide and BSA Free [NBP2-75908]

Western Blot: TNF-alpha Antibody (CDP 571 (Humicade))Azide and BSA Free [NBP2-75908]

Western Blot: TNF-alpha Antibody (CDP 571 (Humicade)) [NBP2-75908] - Rat liver (lane 1), rat spinal cord (lane 2), mouse testis (lane 3), rat colon (lane 4) and human thyroid tumour (lane 5) samples were resolved on a 10% SDS PAGE gel and blots probed with NBP2-75908 at 1 ug/ml before being detected by a secondary antibody. The expected band size for TNFalpha is 26 kDa, however dimers and other higher order complexes are well described in the literature too (c.f. Petersen 1989, PMID: 2583226). NBP2-75908 successfully detected human and rat TNF alpha.

Background: TNF-alpha

Tumor necrosis factor (TNF)-alpha is a pro-inflammatory cytokine belonging to the TNF superfamily that is secreted by monocytes/macrophages, T cell, and natural killer (NK), among others (1). TNF-alpha is synthesized as a 233 amino acid (aa) transmembrane protein (mTNF-alpha) with a theoretical molecular weight (MW) of 26 kDa (1,2) that forms a homotrimer. mTNF-alpha is cleaved by TNF-alpha converting enzyme (TACE) and released in its 157 aa, 17 kDa soluble form (sTNF-alpha) (1-5). Both mTNF-alpha and sTNF-alpha are capable of binding type 1 TNF receptors (TNFR1), whereas mTNF-alpha predominately binds to TNFR2 (1,2). TNF-alpha binding to its receptors causes receptor recruitment of adaptor proteins, formation of signaling complexes, and downstream signaling cascades (e.g. MAPK, NF-kappaB, and Caspase-8), leading to distinct cellular responses such as survival, proliferation, inflammation, necroptosis, and apoptosis (1-5).

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).
