Assay Method Information

Assay Name:  Luciferase-Coupled Chemiluminescence Assay
Description:  Kinase activity is measured as the percent of ATP consumed following the kinase reaction using luciferase-luciferin-coupled chemiluminescence. Reactions were conducted in 384 or 1536-well white medium binding microtiter plates (Greiner). Kinase reactions were initiated by combining test compounds, kinase, and ATP in a 20 μL volume (6 μL volume for 1536-well plate). The reaction mixture was incubated at ambient temperature for 2 h. Following the kinase reaction, a 20 μL (or 3 μL for 1536-well plate) aliquot of KinaseGlo (Promega) was added and the chemiluminescence signal measured using an EnVision plate reader (Perkin Elmer). Total ATP consumption was limited to 25-60% and the IC50 values correlate well with those determined by radiometric assays.
