No. E01A0038 Product Name Human Adenosine Triphosphate ELISA kit Species Human Product Size 48 Tests / 96 Tests Concentration 50-1000 ng/mL Sensitivity 1.0 ng/mL Principal Competitive ELISA Sample Volume 100 ul Sample Type Serum, plasma, cell culture supernatants, body fluid and tissue homogenate Assay Time 90 minutes Platform Microplate Reader Conjugate HRP Detection Method Colorimetric Storage 2-8°C Principle of the Assay ATP ELISA kit applies the competitive enzyme immunoassay technique utilizing an anti-ATP antibody and an ATP-HRP conjugate. The assay sample and buffer are incubated together with ATP-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 ATP concentration since ATP from samples and ATP-HRP conjugate compete for the anti-ATP antibody binding site. Since the number of sites is limited, as more sites are occupied by ATP from the sample, fewer sites are left to bind ATP-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The ATP concentration in each sample is interpolated from this standard curve.
