Description
Intended Uses: This dp-cMGP ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human dp-cMGP. This ELISA kit for research use only, not for therapeutic or test applications!
Principle of the Assay: dp-cMGP ELISA kit applies the competitive enzyme immunoassay technique utilizing an anti-dp-cMGP antibody and an dp-cMGP-HRP conjugate. The assay sample and buffer are incubated together with dp-cMGP-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 dp-cMGP concentration since dp-cMGP from samples and dp-cMGP-HRP conjugate compete for the anti-dp-cMGP antibody binding site. Since the number of sites is limited, as more sites are occupied by dp-cMGP from the sample, fewer sites are left to bind dp-cMGP-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The dp-cMGP concentration in each sample is interpolated from this standard curve
