Abcam’s Free Estriol competitive in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Free Estriol in serum and plasma.
A 96-well plate has been precoated with anti-Estriol IgG. Samples and the Estriol-HRP conjugate are added to the wells, where Estriol in the sample competes with the added Estriol-HRP for antibody binding. After incubation, the wells are washed to remove unbound material and TMB substrate is then added which is catalyzed by HRP to produce blue coloration. The reaction is terminated by addition of Stop Solution which stops the color development and produces a color change from blue to yellow. The intensity of signal is inversely proportional to the amount of Estriol in the sample and the intensity is measured at 450 nm.
Storage instructionsStore at +4°C. Please refer to protocols.
