Case studies combining GTP binding and cAMP assays for greater insight

The GTP Gi binding assay and the cAMP Gi assay enable you to study the GPCR activation response at different levels of the signaling pathway. This application note describes two case studies highlighting the complementary and relevant use of these assays for characterizing a panel of reference compounds ( full agonists, partial agonists, and antagonists)  in two different receptor models.
