Innoprot offers different cell lines stably expressing GPCRs to monitor their activation through different pathways:

  • HiTSeeker Cell Lines express GPCR with no tag
  • Internalization Cell Lines express GPCR tagged to tGFP to monitor internalization assays.
  • Nomad Cell Lines co-express GPCR with no tag and Nomad Biosensors to monitor simultaneously the different GPCR signalling pathways (β-arrestin recruitment, Ca2+, cAMP or also DAG).

D2 Dopamine Receptor Cell Line

cAMPNOMAD D2 Dopamine Receptor Cell Line


cAMPNOMAD Cells are cell lines stably co-expressing tag-free GPCRs and cAMP Nomad Biosensor to monitor G-protein modulation by cAMP release. Each vial of cAMPNOMAD D2 Dopamine Receptor Cell Line contains U2OS cells stably expressing the following constructs:

  • human D2 Dopamine Receptor (DRD2) with no tag
  • cAMP Nomad Biosensor (Red Fluorescence)

cAMPNOMAD DRD2 Cell Line allows to assay compounds analyzing the G-Protein signalling pathway by Go involving receptor activation. When an agonist binds to DRD2, the Go protein is activated which, in turn, triggers a cellular response mediated by cAMP. This leads to an increase of red fluorescence intensity of cAMP biosensor. So, the activity can be easily quantified on living cells in a dose-response manner by fluorescence emission in a microplate reader.
