Description
Principle of the Assay: Anti-AT2R1 ELISAkit applies the competitive enzyme immunoassay technique utilizing Angiotensin 2 Receptor 1 Antigen (Anti-AT2R1) and an Anti-AT2R1-HRP conjugate. The assay sample and buffer are incubated together with Anti-AT2R1-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 Anti-AT2R1 concentration since Anti-AT2R1 from samples andAnti-AT2Rl-HRP conjugate compete for the Angiotensin 2 Receptor 1 Antigen binding site. Since the number of sites is limited, as more sites are occupied by Anti-AT2R1 from the sample, fewer sites are left to bind Anti-AT2R1-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The Anti-AT2R1 concentration in each sample is interpolated from this standard curve
