General description

A 2-arylbenzothiazole compound that acts as an inhibitor against the ATP-dependent Photinus pyralis (lucPpy) and Photuris pennsylvanica (lucPpe) luciferase activity (IC50 = 0.2 and 0.32 µM, respectively, with 10 µM ATP, 10 µM luciferin, and 10 nM respective enzyme). Unlike Luciferase Inhibitor I (Cat. No. 119113), Luciferase Inhibitor II is competitive with respect to luciferin and exhibits reduced potency against lucPpe-based commercial luciferase-luciferin formulations with high luciferin concentration (IC50 = 10 µM against Promega′s Kinase-Glo; ineffective against Kinase-Glo Plus and Kinase-Glo Max; at a 3-fold formulation dilution and 6.77 µM ATP).

Here, we describe an optimized protocol to identify specific nuclear receptor ligands. First, to rule out any compound interference with luciferase activity per se, we describe an in vitro assay assessing potential inhibition or activation of luciferase enzymatic activity. Second
