INTENDED USE This PSA ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Mouse PSA. This ELISA kit for research use only, not for therapeutic or diagnostic applicat ions!
PRINCIPLE OF THE ASSAY PSA ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-PSA antibody and an PSA-HRP conjugate. The assay sample and buffer are incubated together with PSA-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 PSA concentration since PSA from samples and PSA-HRP conjugate compete for the anti-PSA antibody binding site. Since the number of sites is limited, as more sites are occupied by PSA from the sample, fewer sites are left to bind PSA-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The PSA concentration in each sample is interpolated from this standard curve.
