GPCR Functional Screening Services

Functional studies of G-protein coupled receptors (GPCR) are complementary to affinity-based radioligand assays. They provide valuable information about the way a drug interacts with a GPCR receptor. For example, you can determine if a drug is an agonist or an antagonist or what its potency and efficacy are for a given GPCR target. Understanding drug functionality is also an important benefit of functional studies and you can, for example, identify allosteric modulators that are generally difficult to identify using orthosteric ligand-based binding assays.   

GPCRFunctional ™

CDAS' GPCRFunctional platform is a comprehensive suite of functional GPCR services for custom assay development, screening, and profiling across a variety of GPCR targets and specific drug activity studies. GPCRFunctional is based on  PerkinElmer sourced recombinant cell lines and on optimized second messenger assay protocols developed by CDAS. ValiScreen® cell lines express human forms of GPCR targets and preserve the natural coupling of each GPCR target. AequoScreen® cell lines couple human forms of GPCR targets with a calcium response pathway emitting a rapidly decaying flash luminescence.


GPCRFunctional ™ AD

CDAS Molecular and Cell biology groups can assist you with any GPCR target assay development. Whether your project requires the complete creation and validation of a recombinant GPCR expressing cell line model or the optimization of assay conditions for an existing target, we will work closely with you to define the best development strategy (choice of cellular host model, GPCR assay readout)

Our capabilities include:

  • Gene cloning
  • Clone selection and amplification
  • Cell line characterization
  • Optimization of assay method(s)
  • Assay validation
