About This Kit
The Human Tumor Necrosis Factor Alpha (Hu TNF alpha) ELISA kit offers a precise method for quantifying Hu TNF alpha in human serum, plasma, urine, or cell culture medium. The test will exclusively identify both natural and genetically engineered Hu TNF alpha.
Principle of the method
The solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) for Human TNF alpha is engineered to quantify the amount of the target captured between a compatible antibody pair. An antibody specific to the target has been pre-coated in the wells of the provided microplate. Samples, standards, or controls are subsequently introduced into these wells and attach to the immobilized (capture) antibody. The sandwich is completed by the addition of the second (detector) antibody. A substrate solution is then added, which reacts with the enzyme-antibody-target complex to yield a measurable signal. The strength of this signal is directly related to the concentration of the target in the original sample.
Target information
TNF alpha is a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily. This cytokine is mainly secreted by macrophage and bind to its receptors, TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. TNF alpha is involved in the regulation of immune cells, cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. TNF alpha exists as a multimer of two, three, or five noncovalently linked units, but shows a single 17 kDa band following SDS-PAGE under non-reducing conditions. Knockout studies in mice also suggested the neuroprotective function of TNF alpha, and has been observed to causes tumor necrosis when injected into tumor-bearing mice. Other functions of TNF-alpha include its role in the immune response to bacterial, viral, parasitic and certain fungal infections, as well as its role in the necrosis of specific tumors. TNF alpha causes cytolysis or cytostasis of certain transformed cells, being synergistic with interferon-gamma in its cytotoxicity. This cytokine has been implicated in a variety of diseases, including autoimmune diseases, insulin resistance, and cancer.
