The Bioaim Porcine TNF-alpha ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of TNF-alpha in porcine serum, plasma and cell culture media. An antibody specific for porcine TNF-alpha was coated on a 96-well plate. Standards and samples are added to the wells and any TNF-alpha present binds to the immobilized antibody. The wells are washed and biotinylated anti-porcine TNF-alpha antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of TNF-alpha present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Apoptosis; Cancer Biomarker; Cell adhesion; Inflammation;
tumor necrosis factor(TNF α) Background: Tumor necrosis factor alpha (TNF-α), 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-α is produced by a wide variety of immune and epithelial cell types. Human TNF-α shares 97% aa sequence identity with rhesus and 71% – 92% with bovine, canine, cotton rat, equine, feline, mouse, porcine, and rat TNF-α. TNF-α trimers bind the ubiquitous TNF RI and the hematopoietic cell-restricted TNF RII, both of which are also expressed as homotrimers. TNF-α regulates lymphoid tissue development through control of apoptosis. It also promotes inflammatory responses by inducing the activation of vascular endothelial cells and macrophages. TNF-α is a key cytokine in the development of several inflammatory disorders. It contributes to the development of type 2 diabetes through its effects on insulin resistance and fatty acid metabolism.
