The Canine E3 (Estriol)ELISA quantitates E3 in serum and plasma.
原理方法
The Canine Estriol (E3) solid-phase competitive ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of Estriol (E3) in biological samples. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are added into these wells and bind to the immobilized (capture) antibody.
Canine Estriol (E3) in samples (or standards) competes with a fixed amount of Estriol (E3) immobilized on the solid phase for binding to the HRP-linked detection antibody specific to Estriol (E3). Excess conjugate and unbound sample or standard are washed from the plate.
A substrate solution is added that reacts with the enzyme-antibody complex to produce a measurable signal. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The intensity of this signal, measured spectrophotometrically at a wavelength of 450 ± 2 nm, is inversely proportional to the concentration of Estriol (E3) present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

Estriol is the main estrogen in the blood and urine of pregnant females. Serum estriol determinations reflect the status of the fetus and are used to evaluate fetal distress and placental function.
