GPCR Cell Lines
From GPCR cell lines to luciferase-labeled tumor cells for in vivo imaging studies, to engineered cells we offer a wide range of cell lines designed to fit your research and development needs.
GPCR cell lines: Over 300 stable GPCR cells lines for binding and functional testing and over 130 cells lines for calcium testing
- AequoScreen® cell lines are doubly transfected to co-express both Aequorin and a variety of GPCRs for calcium flux assays
- ValiScreen® cell lines express a variety of different GPCRs
- PhotoScreen® cell lines include photoprotein kinetic luminescence technology for measuring calcium flux in cells
Luciferase-labeled tumor cell lines: IVISbrite™ bioluminescent tumor cells, for in vivo imaging, are labeled with red-shifted luciferase that offer a brighter signal
Engineered cell lines: With over 7,500 ‘ready-to-go’ cell lines to custom services, Horizon Discovery has the expertise to provide unrivaled cell line engineering solutions


Tag-lite® binding assays
Revvity's Tag-lite binding assays offer straightforward add-and-read protocols to help you characterize the binding properties of compounds, regardless of their chemical structures (peptides, small or complex molecules), or pharmacological properties (agonist, antagonist, or inverse agonist).
