Cortisol ELISA Kit

A highly sensitive competitive immunoassay for quantitative determination of cortisol in biological fluids. This species-independent kit supports diverse sample types including saliva, urine, serum, plasma (heparin, EDTA), fecal extracts, and dried blood spots (DBS). The assay employs a competitive binding principle where cortisol in standards and samples competes with cortisol conjugated to alkaline phosphatase for binding sites on a polyclonal antibody. Features a wide detection range of 156.25–10,000 pg/mL with sensitivity of 56.72 pg/mL. Ideal for stress research, endocrinology, and behavioral studies across multiple species including human, mouse, rat, and other mammals. Complete results in 3 hours with minimal hands-on time.
