The Canine Pg (Progesterone) ELISA quantitates Pg in serum and plasma.
原理方法
The Canine Progesterone (Pg) solid-phase competitive ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of Progesterone (Pg) 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 Progesterone (Pg) in samples (or standards) competes with a fixed amount of Progesterone (Pg) immobilized on the solid phase for binding to the HRP-linked detection antibody specific to Progesterone (Pg). 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 Progesterone (Pg) 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.

Progesterone is the major progestational steroid, secreted primarily by the corpus luteum and the placenta. Progesterone binds to the progesterone receptor, resulting in dissociation of heat shock proteins, receptor phosphorylation, and transcription activation through direct or indirect interaction with transcription factors. Progesterone acts on the uterus, the mammary glands and the brain. It is required in embryo implantation, pregnancy maintenance, and the development of mammary tissue for milk production. Progesterone, converted from pregnenolone, also serves as an intermediate in the biosynthesis of gonadal steroid hormones and adrenal corticosteroids. Therapeutic progesterone is a synthetic form of the endogenous hormone progesterone. This agent exerts inhibitory effects on estrogens by decreasing the number of estrogen receptors and increasing its metabolism to inactive metabolites. [National Center for Biotechnology Information.
