Description
Assay Principle:
The Corticosterone Chemiluminescent ELISA Kits quantitatively measure corticosterone in Serum, Plasma, Urine, Respiratory Vapor, Fecal Extracts, Feathers, Hair, and Tissue Culture Media. The Corticosterone Chemiluminescent ELISA Kits are a competitive ELISA with a run time of 2 hours. Please read the complete kit insert for more information before performing this assay.
Use our provided corticosterone standard to generate a standard curve for the assay. Pipette the standards or diluted samples into a transparent microtiter plate coated with our donkey anti-sheep IgG antibody. Add the corticosterone peroxidase conjugate and the corticosterone polyclonal sheep antibody. Then incubate the mixture for 2 hours, shaking at room temperature. The immunological reaction occurs between the anti-corticosterone polyclonal antibody, the corticosterone antigen in the sample or standard, and the corticosterone-peroxidase conjugate. As the corticosterone concentration in the sample increases, the bound corticosterone-peroxidase conjugate decreases, causing a decrease in signal and vice versa.
After the 2-hour incubation, wash away the excess corticosterone-peroxidase and add the chemiluminescent substrate. The chemiluminescent substrate reacts with the bound corticosterone-peroxidase conjugate generating a light detected by a plate reader. Use the intensity and the standard curve to calculate the corticosterone concentration in the samples.
Background:
Corticosterone (Kendall’s Compound ‘B’) is a steroid hormone secreted by the cortex of the adrenal gland. The adrenal cortex produces this Aldosterone precursor, Corticosterone, upon ACTH stimulation. Corticosterone is a significant indicator of stress and is the prominent stress steroid produced in non-human mammals. Studies involving corticosterone and stress levels have found evidence of impairment of long-term memory retrieval. Corticosterone levels are also elevated in response to burn injuries and drastic dietary restrictions. In addition to stress levels, Corticosterone plays a decisive role in sleep-wake patterns. Corticosterone also plays significant developmental and behavioral functions in birds.
