Application This ELISA kit applies to the in vitro quantitative determination of Cortisol concentrations in serum, plasma, urine, saliva.

Test Principle

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Human Cortisol. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human Cortisol are added to the micro ELISA plate wells. Human Cortisol in samples (or standards) competes with a fixed amount of Cortisol on the solid phase supporter for sites on the HRP linked detection antibody specific to Cortisol. Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450±2 nm. The concentration of Human Cortisol in the samples is then determined by comparing the OD of the samples to the standard curve.

Kit components & Storage

An unopened kit can be stored at 2-8℃ for 6 months. After test, the unused wells and reagents should be stored according to the table.

Technical Data

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Cortisol were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Cortisol were tested on 3 different plates, 20 replicates in each plate.

Recovery

The recovery of Cortisol spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

Sample Type Range (%) Average Recovery (%)
Serum(n=8) 84-96 90
EDTA plasma(n=8) 90-103 96
Urine(n=8) 91-109 99

Linearity

Samples were spiked with high concentrations of Human Cortisol and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
