TNF-α is a pleiotropic pro-inflammatory cytokine secreted by various cells, including adipocytes, activated monocytes, macrophages, B cells, T cells and fibroblasts.
It belongs to the TNF family of ligands, and signals through two receptors, TNFR1 and TNFR2.
TNF-α is cytotoxic to a wide variety of tumor cells, and is an essential factor in mediating the immune response against bacterial infections.
TNF-α also plays a role in the induction of septic shock, autoimmune diseases, rheumatoid arthritis, inflammation, and diabetes.
Human and murine TNF-α demonstrate significant cross-species reactivity.
TNF-α exists in two forms; a type II transmembrane protein, and a mature soluble protein.
The TNF-α transmembrane protein is proteolitically cleaved to yield a soluble, biologically active, 17 kDa TNF-α, which forms a non-covalently linked homotrimer in solution.
The BioGems Human TNF-α Pre-Coated ELISA （Enzyme-Linked Immunosorbent Assay） kit is a solid phase immunoassay specially designed to measure Human TNF-α with a 96-well strip plate that is pre-coated with mouse monoclonal antibody specific for TNF-α.
It contains E.coli-expressed recombinant Human TNF-α.
The detection antibody is a biotinylated goat polyclonal antibody specific for TNF-α.
The kit is analytically validated with ready to use reagents.
