COMPONENTS	96-well polystyrene enzyme-linked immunosorbent assay (ELISA) plate coated with anti-IL-4 monoclonal antibody Human IL-4 freeze-dried standard IL-4 detect Antibody Standard Diluent Assay Buffer(10×) Substrate TMB Stop Solution Washing Buffer(20×) Sealing Film
ASSAY PRINCIPLE	This kit utilizes the double antibody sandwich enzyme-linked immunosorbent assay (ELISA) detection technique.Specific anti-human IL-4 antibodies are precoated on a high-affinity ELISA plate. Standard samples, test samples, and biotinylated detection antibodies are added to the wells of the ELISA plate. After incubation, IL-4 present in the samples binds to the solid-phase antibodies and the detection antibodies. After washing to remove unbound substances, streptavidin-HRP labeled with horseradish peroxidase is added. After washing, a colorimetric substrate, TMB, is added and the plate is incubated in the dark for color development. The intensity of the color reaction is directly proportional to the concentration of IL-4 in the samples. A stop solution is added to terminate the reaction, and the absorbance value is measured at a wavelength of 450 nm (with a reference wavelength range of 570-632 nm).
