Luciferase reporter assay systems are successfully used in the
drug discovery process against G-protein coupled receptors for both studying the
GPCR signaling pathways and for screening for modulators of GPCRs. Here we
describe a strategy for constructing stable cell lines expressing two
luciferases on two plasmids that reduces assay noise and false positives when
screening for downregulated responses (antagonist response of GPCR).
