  • Product overview

    Corticosterone in vitro competitive ELISA (Enzyme-Linked Immunosorbent Assay) kit (ab108821) is designed for the quantitative measurement of Corticosterone levels in plasma, serum, urine, milk, saliva and cell culture supernatant.

    A Corticosterone specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently biotinylated Corticosterone is added and then followed by washing with wash buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is inversely proportional to the amount of Corticosterone captured in plate.

    Corticosterone is the adrenal steroid, the major glucocorticoid. Glucocorticoid hormones are also known as corticosteroid hormones and are synthesized mainly in the adrenal cortex; however, more recently the enzymes involved in their synthesis have been found in a variety of cells and tissues, including the heart. The effects of these hormones are mediated via both cytoplasmic mineralocorticoid receptors (MRs) and glucocorticoid receptors (GRs), which act as ligand-inducible transcription factor. Corticosterone has profound effect on the structure and function of the hippocampus. Brain corticosterone action through the glucocorticoid receptor may involve memory storage. Emotional stress might cause increases in plasma corticosterone.


Our Abpromise guarantee covers the use of ab108821 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

We are happy to help! :-)
I wish you success with your experiments and a good weekend.

Thank you for your email.
I am happy to send you the results of your experiments today. They were put in our program by one of our Lab members that is responsible for our ELISA testing and optimizing etc. As discussed on the phone this is a one-of...

Thank you for contacting us.
The kit ab108821 utilizes the corticosterone specific antibodies. This kit cannot be used to detect the CBG (transcortin) corticosteroid-binding globulin in samples.
I hope this information is helpful to you. Plea...

I think the results that the customer got is perfectly normal. ab108821 is a "competitive" ELISA. Step 2 of the flowchart on page 5 of the protocol, standard or sample is added together with a "biotinylated corticoster...

I have checked with my colleague, and could offer you either 20% off a primary antibody OR 20% off a protein/peptide product - for trying the kit in mouse brain.

Please let me know which one of these of...
