Principle of Assay
Human Endoglin ELISA Kit is based on the quantitative sandwich enzyme-linked immunosorbent assay technique to measure concentration of human Endoglin in the samples. A monoclonal antibody specific for human Endoglin has been immobilized onto microwells. Standard or samples are pipetted into the wells, followed by the addition of biotin-linked detect antibody specific for Endoglin, and Endoglin 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 Endoglin bound by the immobilized antibody. The color development is stopped by addition of acid and the optical density value is measured by microplate reader.
