Description
Principle of the Assay: PPARgamma ELISA kit applies the competitive enzyme imnnmoassay technique utilizing a monoclonal anti-PPARgamma antibody and an PPARgamma-HRP conjugate. The assay sample and buffer are incubated together with PPARgamma-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times The wells are men 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 rum the solution yellow. The intensity of color is measured spectrophotometrically at 450om in a microplate reader. The intensity of the color is inversely proportional to the PPARgamma concentration since PPARgamma from samples and PPARgamma-HRP conjugate compete for the anti-PPARgamma antibody binding site. Smce the number of sites is limited, as more sites are occupied by PPARgamma from the sample, fewer sites are left to bind PPARgamma-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The PPARgamma concentration in each sample is interpolated from this standard curve
