The Cortisol EIA kit is a colorimetric competitive enzyme immunoassay kit for the quantitative determination of cortisol in culture supernatants, plasma, serum, saliva, and urine from any species.

• Trusted - highly cited in peer reviewed literature
• Reproducible results day-after-day and lot-after-lot
• Highly sensitive, detecting low levels of cortisol in biological matrices
• Pre-coated plates and liquid colour coded reagents save time and reduce errors

Absorbance is read at 405 nm. The broad dynamic range allows accurate measurement of cortisol levels in a variety of sample matrices.
