Notes: The authors of this paper introduce a luminescent assay to monitor changes in cellular cAMP concentration. The assay can be used to study the activity of G-protein coupled receptors that modulate adenylate cyclase activity. The assay is compatible with high-throughput screening in 96-, 384- and 1536-well formats. (3928)

Notes: The authors of this paper review bioluminescent assay technologies, discussing HTS reporter, cell-based and luciferase biosensor assays. They divide luminescent assays into three basic categories: assays that measure ATP concentration (cell viability and kinase assays), assays that measure changes in luciferase levels (reporter assays, GPCR assays), and assays that measure changes in luciferin levels (protease [including caspase], P450 and MAO assays).
