Key Features
Potency-Oriented
Characterizes compounds' potency, not affinity, on the G-protein pathways of the target GPCR in various modes
Super-Sensitive
Dramatically and specifically amplifies G-protein-dependent signals
All-Around
All GPCRs are amenable in single assay format, regardless of Gα proteins coupled
