M2R fluorescence-based biosensor panel
Construct PatternHere we use genetic code expansion and bioorthogonal labelling to generate a panel of fluorescence-based biosensors for a prototypical GPCR, the M2 muscarinic acetylcholine receptor (M2R). These biosensors enable real-time monitoring of agonist-promoted conformational changes across the receptor's extracellular surface in intact cells.
