  • SpecificityThis assay has high sensitivity and excellent specificity for detection of IFN beta1b. No significant cross-reactivity or interference between IFN beta1b and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between IFN beta1b and all the analogues, therefore, cross reaction may still exist in some cases.

  • Product Description
    Principle of the assay: IFN beta1b ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-IFN beta1b antibody and an IFN beta1b-HRP conjugate. The assay sample and buffer are incubated together with IFN beta1b-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 IFN beta1b concentration since IFN beta1b from samples and IFN beta1b-HRP conjugate compete for the anti-IFN beta1b antibody binding site. Since the number of sites is limited, as more sites are occupied by IFN beta1b from the sample, fewer sites are left to bind IFN beta1b-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The IFN beta1b concentration in each sample is interpolated from this standard curve.
