Products for receptor binding
Receptor binding assays involve the binding of a ligand to a specific receptor that is usually supplied in a membrane preparation. The ligand is generally labeled with a radioactive isotope when using Scintillation Proximity Assays (SPA) for example, or a fluorescent moiety when measuring assays such as fluorescence polarization.
GE Healthcare provides a wide range of radioactive ligands, assays and fluorescent products to address GPCR ligand binding and enable flexibility of choice
Assays:
 GTPgS assay - Identify inhibitors of ligands that are active at G protein-coupled receptors and is fully amenable to automation for high-throughput screening. |
Radiometric Imaging Beads - CCD Imagers
SPA Imaging beads are microspheres containing scintillant which emit light in the red region of the visible spectrum. As a result, these beads are ideally suited to use with a CCD imager |

Radiometric Imaging Beads - General research
SPA Scintillation beads are microspheres containing scintillant which emit light in the blue region of the visible spectrum. As a result, these beads are ideally suited to use with photomultiplier tube (PMT) counters such as the TopCount™ or MicroBeta™. |
