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).
