Tumor Necrosis Factor Receptor 1, p55 (TNFR 1, CD120a, MGC19588, p55, p55 R, TNFR55, Tumor Necrosis Factor alpha Receptor, Tumor Necrosis Factor Binding Protein 1, TBP1, Tumor Necrosis Factor Receptor Superfamily Member 1A, TNFRSF1a)

Tumor necrosis factor alpha (TNFalpha), also known as cachectin, is a 17.5kD, 157 amino acid member of the TNF superfamily of cytokines that is a potent lymphoid factor with effects on a wide range of target cells. Active TNFalpha is produced in both soluble and membrane-anchored trimers by macrophages, NK cells, and T- and B-lymphocytes. TNF exerts proinflammatory signals via binding and inducing trimerization of TNF-receptor 1 (TNFR 1) expressed on most normal and transformed cells, or to TNF-receptor 2 (TNFR 2), expressed on endothelial and most immune cells. TNF signaling regulates hematopoiesis, differentation, endothelial cell activation, apoptosis, lipid metabolism, tumor progression, and immune suveillance, and dysregulation of TNF or its receptors is implicated in numerous disease states including cancer, osteoporosis, autoimmune disease, diabetes, and atherosclerosis.||Applications:|Suitable for use in ELISA, Western Blot, Immunoprecipitation, and Immunohistochemistry.
