Assay Method Information

Assay Name:  In Vitro Enzyme Inhibition Assay
Description:  Compounds in 100% DMSO were added to assay plates by acoustic dispensing. PI3Kβ was added in a Tris buffer (50 mM Tris pH7.4, 0.05% CHAPS, 2.1 mM DTT, and 10 mM MgCl2) and allowed to preincubate with compound for 20 minutes prior to addition of substrate solution containing PIP2 and ATP. The enzyme reaction was stopped after 80 minutes by the addition of Kinase Glo detection solution. Plates were left for 30 minutes at room temperature then read on a Pherastar Instrument (Luminescence ATP 384 program) setting gain on max well. The final concentration of DMSO, ATP and PIP2 in the assay were, 1%, 8 μM, and 80 μM respectively.
