Rat COR (Cortisol) ELISA Kit (RTFI01429)

Cortisol is the principal glucocorticoid stress hormone circulating in rat blood, and quantitative measurement of circulating levels supports research into hypothalamic-pituitary-adrenal (HPA) axis activity, circadian rhythm regulation, and responses to physiological or pharmacological challenges. This competitive ELISA kit from Assay Genie is configured for quantitative cortisol determination in rat-derived biological samples, providing a microplate-based colorimetric workflow that runs in vitro on serum or plasma specimens.

Each kit supplies reagents sufficient for 96 determinations in a standard microplate footprint, with all components formulated for refrigerated storage to preserve antibody binding activity through the stated shelf life. The assay exploits competition between sample cortisol and a labelled cortisol conjugate for limited antibody binding sites, producing an inverse absorbance signal relative to analyte concentration.

Researchers studying adrenal function, behavioural stress paradigms, endocrine disruption models, or metabolic phenotyping in rats will find this reagent set useful for generating reproducible concentration data from small-volume samples. The kit is intended for research use only and is not validated for diagnostic or clinical applications in humans or animals.
