The Rat Progesterone (Pg) ELISA quantitates Pg in serum and plasma.
Principle of the method
The Rat Pg 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 Rat Pg. 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 Rat Pg 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 Rat Pg present in the original specimen, which is determined by comparing the OD of the samples to the standard curve.

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.
