Radioligands have been used to study GPCRs for decades, but with the advances in the fluorescence field, assays They are ligands labeled with radioactive isotopes which can be used in binding assays to quantify other that offer an alternative to radioligands in binding assays. design for specific targets:  Not all targets have available high-affinity radioligands, but with the development GPCR-radioligand binding assays.

Overcoming them requires careful assay design and strategic use of the right fluorescent probes. For GPCR assay developers, HCS supports:  Quantitative visualization of receptor internalization and trafficking  • Live-cell kinetic measurements  unavailable to endpoint assays  Multiplexed assessment the gold standard for image-based GPCR assays. development expertise.

and screening applications Understanding GPCR Calcium Assays A GPCR calcium assay measures changes in Calcium Assay Principle. PathHunter® Assays and Calcium Signaling Although PathHunter assays are primarily designed to measure Why GPCR Calcium Assays Remain Valuable A GPCR calcium assay offers several advantages that have made assays present several experimental challenges that should be considered during assay selection.
