Abstract

Cyclic adenosine monophosphate (cAMP) is an intracellular signaling messenger derived from the catalytic conversion of ATP, and is a major product of activated Gs protein-coupled receptors. Conversely, formation of cAMP is inhibited by Gi protein-coupled receptors. This protocol has been optimized for the detection of ligand-mediated cAMP accumulation in adherent immortal cell lines expressing Gs-coupled receptors.
