About This Kit
The Human Estradiol (E2) ELISA quantitates E2 in serum, plasma, urine, saliva.
Principle of the method
The Human E2 solid phase competitive ELISA (enzyme linked immunosorbent assay) is designed to measure the amount of the target bound between the pre coated antigen and the HRP linked antibody specific for Human E2. A target specific antigen has been pre coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells, where Human E2 in the samples (or standards) competes with the immobilized (capture) antigen for sites on the HRP linked detection antibody. Excess conjugate and unbound sample or standard are washed away from the plate. The substrate solution is added to each well, and the enzyme substrate reaction is terminated by the addition of a stop solution, turning the color yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450±2 nm. The intensity of this signal is inversely proportional to the concentration of Human E2 present in the original specimen, which is determined by comparing the OD of the samples to the standard curve.

Target information
Estradiol (17 beta-estradiol) is a sex hormone. Estradiol is the predominant sex hormone present in females. It is also present in males, being produced as an active metabolic product of testosterone. It represents the major estrogen in humans. Estradiol has not only a critical impact on reproductive and sexual functioning, but also affects other organs including the bones.
