ELISA Kit PrincipleAviva Systems Biology Estradiol ELISA Kit (Fish) (OKCA00350) is based on a competitive enzyme immuno assay technique. The microtiter plate provided in this kit has been pre-coated with goat-anti-rabbit antibody. Standards or samples are added to the appropriate microtiter plate wells with an antibody specific for Estradiol and Horseradish Peroxidase (HRP) conjugated Estradiol. The competitive inhibition reaction is launched between with HRP labeled Estradiol and unlabeled Estradiol with the antibody. A substrate solution is added to the wells and the color develops in opposite to the amount of Estradiol in the sample. The color development is stopped and the intensity of the color is measured.

Protein NameEstradiol
Description of TargetEstradiol is the 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position. Estradiol-17-beta is the most potent form of mammalian estrogenic steroids. Estradiol is an Estrogen. The mechanism of action of estradiol is as an Estrogen Receptor Agonist. The chemical classification of estradiol is Estradiol Congeners. Therapeutic Estradiol is a steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females. Typically esterified, estradiol derivatives are formulated for oral or parenteral administration. As the primary, most potent estrogen hormone produced by the ovaries, estradiol binds to and activates specific nuclear receptors. Estradiol exhibits mild anabolic and metabolic properties, and increases blood coagulability.
