AequoScreen® Parental cells stably expressing the mitochondrially targeted apoaequorin and the G-protein Gqi5 for flash-luminescence assay.
Recombinant, in CHO-K1 host cell. GPCRs of your choice can be transiently / stably transfected into these cell lines. Following GPCR stimulation, increases in intracellular calcium enable measurement of the resulting flash luminescence signal. Two vials of cryopreserved cells are shipped per order.


  • Functional, homogenous and generic assay platform for Gi coupled GPCRs
  • Fully automatable and miniaturizable to 1536
  • Enables reduction in reagents and consumable costs
  • High signal to background ratio enabling detection of agonists, antagonists and allosteric modulators
  • Robust assay (Z, CV values, solvent resistance)
  • Reduces the number of false positives from autofluorescent compounds in screening libraries
  • Option to work with cells in suspension to increase throughput
