The kit uses a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) to assay the level of Rat Dehydroepiandrosterone sulfate(DHEAS) in samples. Add Dehydroepiandrosterone sulfate(DHEAS) to monoclonal antibody Enzyme well which is pre-coated with Rat Dehydroepiandrosterone sulfate(DHEAS)monoclonal antibody, incubation; then, add Dehydroepiandrosterone sulfate(DHEAS)antibodies labeled with biotin, and combined with Streptavidin-HRP to form immune complex; then carry out incubation and washing again to remove the uncombined enzyme. Then add Chromogen Solution A, B, the color of the liquid changes into the blue, And at the effect of acid, the color finally becomes yellow. The chroma of color and the concentration of the Rat Dehydroepiandrosterone sulfate(DHEAS) of sample were positively correlated. Standard; 240pg/ml.
