  • SpecificityThis assay has high sensitivity and excellent specificity for detection of PDS. No significant cross-reactivity or interference between PDS and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between PDS and all the analogues, therefore, cross reaction may still exist in some cases.

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