Principle of Assay
14,15 EET/DHET ELISA Kit (A326313) employs the competitive enzyme immunoassay technique for the quantitative measurement of 14,15 EET/DHET in serum, plasma, cell culture supernatant, cell or tissue lysate, and other liquid samples. The 96-well microtiter plate has been pre-coated with 14,15 EET/DHET antigen. During the incubation, 14,15 EET/DHET present in the samples or standards competes with the fixed amount of immobilized 14,15 EET/DHET for binding sites on the Biotinylated Anti-14,15 EET/DHET Antibody. The more 14,15 EET/DHET present in a sample or standard, the less Biotinylated Anti-14,15 EET/DHET Antibody that binds to the plate. Following incubation, unbound Biotinylated Anti-14,15 EET/DHET Antibody is removed by washing, and an HRP-Streptavidin conjugate is added to the wells and the microtiter plate is incubated. Following incubation and washing, TMB substrate solution is then used to visualize the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is inversely proportional to the amount of 14,15 EET/DHET present in each sample or standard. The concentration of 14,15 EET/DHET can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
