Product overview
cAMP Assay Kit ab138880 uses a sensitive fluorometric competitive ELISA method to quantify cAMP (cyclic AMP) levels in samples from mammals and other species.
The cAMP assay protocol uses a 96-well plate supplied coated with an anti-cAMP antibody.
HRP-labeled cAMP, and free cAMP within a sample, are added to each well of the plate. The cAMP assay is based on the competition between the HRP-labeled cAMP and the free cAMP for the fixed number of cAMP antibody binding sites on the plate.
The more free cAMP is present, the less HRP-labeled cAMP is bound. After a washing step, the amount of bound HRP-labeled cAMP is detected using a fluorometric HRP substrate. The level of signal is compared to a standard curve for free cAMP, which is run at the same time as the samples.
Unlike other cAMP assay protocols, this kit does not require an acetylation step to achieve the maximum sensitivity.

Relevance
Adenosine 3’,5’-cyclic monophosphate (cyclic AMP, cAMP) is an important “second messenger” involved in many physiological processes. It plays a key role as an intracellular second messenger for transduction events that follow a number of extracellular signals. -
