Humain IL-4 Kit Elisa (A1470)

Human IL-4 ELISA Kit

Sandwich (quantitative)

Human IL-4 ELISA Kit is based on the quantitative sandwich enzyme-linked immunosorbent assay technique to measure concentration of human IL-4 in the samples. A monoclonal antibody specific for human IL-4 has been immobilized onto microwells. Standard or samples are pipetted into the wells, followed by the addition of biotin-linked monoclonal antibody specific for IL-4, and IL-4 present is bound by the immobilized antibody and detect antibody following the first incubation. After removal of any unbound substances, streptavidin-HRP is added for a second incubation. After washing, substrate solution reacts with HRP and color develops in proportion to the amount of IL-4 bound by the immobilized antibody. The color development is stopped by addition of acid and the optical density value is measured by microplate reader.
