Application Note: Quantifying Fluorescent Ligand Binding to GPCRs in Live Cells using the PHERAstar FS - a new format for HTS
17 January 2013

In this application note the PHERAstar FS from BMG LABTECH is used to rapidly and robustly quantify fluorescent ligand binding to live cells expressing recombinant human GPCRs in 96-well format using a simple ‘add > mix > wash > read’ assay protocol. This method is analogous to whole-cell radioligand binding assays, but with inherent safety and cost advantages. It also offers considerable read and analysis time saving advantages over HCA assays, potentially making this format suitable for high throughput screening (HTS).
