| | Inhibition on PI3K Kinase Activity |
| Description: | The activity of purified kinase was detected with Kinase-Glo Plus kinase luminescent assay by measuring the amount of the remaining Kinase in the solution after the kinase reaction was completed. Kinase reaction was performed in a 384-well white plate (Greiner), 1 μL of tested compound or control DMSO was added into each well containing 5 μL reaction buffer [10 mM Tris-HCl pH 7.5, 50 mM NaCl, 3 mM MgCl2.1 mM DTT (dithiothreitol), 0.05% CHAPS (3-[(3-Cholamidopropyl)dimethylammonio]-1-propanesulfonate, 3-(3-cholaminopropyl)-dimethylamino-1-propanesulfonic acid), and the reaction buffer was supplemented with 12 μM of substrate, D-myo-Phosphatidylinositol-4,5-bisphosphate (4,5-phosphatidyl inositol diphosphate) and 2 μM ATP (adenosine triphosphate). And then 4 μL reaction buffer containing 62.5 nM PI3Kα or non-PI3Kα control was added to initiate the kinase reaction. After reaction was performed for 1 hour at room temperature, 10 μL of Kinase Glo-Plus mixture was added and incubated for 1 hour to quench the reaction. The chemiluminescence value was detected with EnVision 2104 multifunctional microplate reader (Perkinelmer). |
