INTENDED USE This PANDER ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Sheep PANDER. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
PRINCIPLE OF THE ASSAY PANDER ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-PANDER antibody and an PANDER-HRP conjugate. The assay sample and buffer are incubated together with PANDER-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 ofcolor is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the PANDER concentration since PANDER from samples and PANDER-HRP conjugate compete for the anti-PANDER antibody binding site. Since the number of sites is limited, as more sites are occupied by PANDER from the sample, fewer sites are left to bind PANDER-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The PANDER concentration in each sample is interpolated from this standard curve
