G protein-coupled receptors (GPCRs) play a crucial role in various cellular and physiological processes, including cell proliferation, differentiation, neurotransmission, development, and apoptosis. GPCR activity is commonly assessed by measuring levels of intracellular cAMP upon stimulation by agonists. Abnormal GPCR activity is associated with many diseases, including cancer, making GPCRs an important class of pharmaceutical drug targets.

Multiple assay formats have been developed to measure the level of cAMP generated, which can determine the pharmacological potency of different agonists and antagonists. The ideal assay is homogeneous, non-radioactive, and allows for sensitive and reproducible detection. AlphaScreen^™ technology provides a quantitative detection of molecules in a homogeneous, no-wash format and can be applied to GPCR research.
