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

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