Cayman’s cAMP assay is a very sensitive competitive ELISA that permits cAMP measurements within the standard curve range of 0.078-10 pmol/ml, typically with a sensitivity (80% B/B0) of 0.1 pmol/ml once samples and standards have been acetylated prior to analysis. This assay has been validated with culture media, urine, tissue, and plasma samples. If you prefer to assay your samples and still achieve excellent sensitivity without the need to perform a pre-assay acetylation step we recommend using Cayman’s cAMP Select ELISA Kit.
