INTENDED USE This GKN1 ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Monkey GKN1. This ELISA kit for research use only!
PRINCIPLE OF THE ASSAY GKN1 ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with a monoclonal antibody specific for GKN1. Standards or samples are then added to the microtiter plate wells and GKN1 if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount of GKN1 present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated polyclonal antibody, specific for GKN1 are added to each well to “sandwich” the GKN1 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 GKN1 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 GKN1 concentration in each sample is interpolated from this standard curve.
