RESUMO
Quantitative measurement of receptor signaling by different ligands is important for understanding the mechanism of drug action and screening of drugs. Here, we describe a simple and cost-effective method of measuring adenylyl cyclase inhibition, one of the hallmarks of opioid receptor activation. The assay is based on bioluminescence resonance energy transfer (BRET) that involves transfection of a biosensor in human embryonic kidney (HEK)-293 cells stably transfected with µ-opioid receptor (µ receptor), enabling real-time measurement of cAMP levels.
