Product Description
specificalPrinciple of the Assay: gamma IFN-Ab ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with Interferon gamma antigen (gamma IFN-Ab) . Standards or samples are then added to the microtiter plate wells and gamma IFN-Ab if present, will bind to the antigen pre-coated wells. In order to quantitatively determine the amount of gamma IFN-Ab present in the sample, a standardized preparation of horseradish peroxidase (HRP) -conjugated Interferon gamma antigen (gamma IFN-Ab) are added to each well to "sandwich" the gamma IFN-Ab immobilized on the plate. The microtiter plate undergoes incubation, and then the wells are thoroughly washed to remove all unbound components. Next, substrate solutions are added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain gamma IFN-Ab and enzyme-conjugated antibody will exhibit a change in color. The enzyme-substrate reaction is terminated by addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The gamma IFN-Ab concentration in each sample is interpolated from this standard curve.
