Assay Platform

Key Features


Characterizes compounds’ potency, not affinity, on target GPCR in various modes


Dramatically and specifically amplifies G-protein-dependent signals


All GPCRs are amenable in single assay format, regardless of Gα proteins coupled


  • On-target and off-target screening for drug discovery
  • Compound profiling
  • Strategy development
  • In-licensing assessment
  • Drug repurposing
