Target
Estriol (also oestriol) is one of the three main estrogens produced by the human body. Estriol (E3) is only produced in significant amounts during pregnancy as it is made by the placenta from 16-Hydroxydehydroepiandrosterone sulfate (16-OH DHEAS), an androgen steroid made in the fetal liver and adrenal glands. The human placenta produces pregnenolone and progesterone from circulating cholesterol. Pregnenolone is converted in the fetal adrenal gland into dehydroepiandrosterone (DHEA), a C19 steroid, then subsequently sulfonated to dehydroepiandrosterone sulfate (DHEAS) . DHEAS is converted to 16-OH DHEAS in the fetal liver. The placenta converts 16-OH DHEAS to estriol, and is the predominant site of estriol synthesis.

Assay Principle
Aviva Systems Biology Estriol ELISA Kit (OKEH02535) is based on a competitive enzyme immunoassay technique. The microtiter well-plate in this kit has been pre-coated with an anti-Estriol antibody. Sample or standards are added to the wells along with a fixed quantity of biotinylated Estriol and incubated. The Estriol found in the sample or standards competes with the biotinylated Estriol for limited binding sites on the immobilized anti-Estriol antibody. Excess unbound biotinylated Estriol and sample or standard Estriol is washed from the plate. Avidin-HRP conjugate is added, incubated and washed. An enzymatic reaction is then produced through the addition of TMB substrate which is catalyzed by the immobilized HRP to generate a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration is measured by reading the absorbance at 450 nm which is quantitatively proportional to the amount of biotinylated Estriol captured in the well and inversely proportional to the amount of Estriol which was contained in the sample or standard.
