Multiplexed profiling of GPCR activities by combining split TEV assays and EXT-based barcoded readouts. the cAMP-adenosine pathway where cAMP is converted to adenosine via ecto-PDEs and ectonucleotidases. The assay was performed according to kit documentation. Forskolin is shown to activate adenylate cyclase at EC50 of 5-10 µM. For G i-coupled receptors, the 22F construct has shown increased S/B in the presence or absence of added forskolin; saturation effects can hinder the 20F construct in the presence of forskolin in select experimental systems (Figure 6). However, agonist ligands for G i-coupled receptors are difﬁcult to track because inducers such as forskolin (FSK) must be used and are sources of variations and errors.
