KTE0002 | EliKine™ Progesterone ELISA Kit — Precision Steroid Hormone Quantification for Reproductive and Endocrine Research

Progesterone: The Master Regulator of Reproduction and Beyond

Progesterone is far more than a "pregnancy hormone." This endogenous steroid and progestogen sex hormone orchestrates the menstrual cycle, sustains pregnancy, guides embryogenesis, and even modulates brain function as a neurosteroid[reference:0]. As a crucial metabolic intermediate in the biosynthesis of other endogenous steroids—including sex hormones and corticosteroids—progesterone sits at the crossroads of multiple endocrine pathways[reference:1]. Whether you are investigating polycystic ovary syndrome (PCOS), evaluating endocrine-disrupting chemicals, or developing novel reproductive therapeutics, accurate progesterone quantification is non-negotiable.

Competitive ELISA Technology: Precision Where It Matters Most

The EliKine™ Progesterone ELISA Kit (KTE0002) employs the competitive inhibition enzyme immunoassay technique[reference:2]. The microtiter plate is pre-coated with goat-anti-rabbit antibody. Standards or samples are added alongside an antibody specific for progesterone and HRP-conjugated progesterone[reference:3]. A competitive inhibition reaction is launched between HRP-labeled progesterone and unlabeled progesterone for the antibody binding sites[reference:4]. The more progesterone present in your sample, the less HRP-conjugated progesterone binds—and the weaker the color development[reference:5]. This inverse relationship delivers quantitative precision across a broad dynamic range.

Broad Species Reactivity: One Kit, Multiple Models

With reactivity spanning Bovine, Chicken, Dog, Goat, Human, Monkey, Rabbit, Rat, Sheep, and Swine[reference:6], KTE0002 eliminates the need for species-specific optimization. Whether you are working with human clinical samples, rat toxicology models, or porcine reproductive studies, this single kit delivers consistent, reliable results.

No Significant Cross-Reactivity — Data You Can Trust

The EliKine™ Progesterone ELISA Kit has been rigorously validated for high sensitivity and excellent specificity[reference:15]. No significant cross-reactivity or interference between progesterone and its analogues was observed[reference:16]. When your data needs to withstand peer review, this is the kit that delivers.
