Description
Intended Uses: This 5-LO/LOX ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Bovine 5-LO/LOX. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
Principle of the Assay: 5-LO/LOX ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-5-LO/LOX antibody and an 5-LO/LOX-HRP conjugate. The assay sample and buffer are incubated together with 5-LO/LOX-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the 5-LO/LOX concentration since 5-LO/LOX from samples and 5-LO/LOX-HRP conjugate compete for the anti-5-LO/LOX antibody binding site. Since the number of sites is limited, as more sites are occupied by 5-LO/LOX from the sample, fewer sites are left to bind 5-LO/LOX-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The 5-LO/LOX concentration in each sample is interpolated from this standard curve
