ELISA 5-hydroxyeicosatetraenoic acid (5-HETE)

Reactivity: (Homo sapiens) UniProt:N/A Abbreviation:5-HETE Alternative Names:N/A Application:ELISA Range:31.25-2000 pg/mL Sensitivity:7.81 pg/mL Intra-AssayCV:?4.3% Inter-AssayCV:?7.5% Recovery:1.02 Sample Type:Serum, Plasma, Other biological fluids Detection Method:Sandwich Analysis Method??:Quantitive Test principle:This assay employs a two-site sandwich ELISA to quantitate 5-HETE in samples. An antibody specific for 5-HETE has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any5-HETE present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjµgated antibody specific for 5-HETE is added to the wells. After washing, Streptavidin conjµgated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of 5-HETE bound in the initial step. The color development is stopped and the intensity of the color is measured. Product Overview:5-Hydroxyeicosatetraenoic acid (5-HETE) is an endogenous eicosanoid. 5-HETE is an intermediate in the pathway of leukotriene synthesis. In addition, it is a modµLator of tubµLoglomerµLar feedback. 5-Hydroxyeicosatetraenoic acid is a key intermediate of the arachidonate-dependent protective signaling in monocytes/macrophages exposed to peroxynitrite. Peroxynitrite elicited the nuclear membrane translocation of 5-LO and enhanced its enzymatic activity via a mechanism sensitive to low concentrations of inhibitors of 5-LO or the 5-LO-activating protein, as well as to genetic depletion of the latter enzyme. Inhibition of 5-LO activity was invariably associated with the cytosolic localization of PKC, the mitochondrial accumµLation of Bad, and a rapid MPT-dependent necrosis. All these events were prevented by nanomolar concentrations of the 5-LO product 5-hydroxyeicosatetraenoic acid. Stability:The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calcµLated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).
