In Vitro Kinase Inhibition Assay: In vitro kinase assay analysis may be performed using standard techniques described in the art. These techniques are also used by commercial services providers in order to offer in vitro kinase activity assay services, e.g. the assays offered by Millipore Inc. (worldwide website www(dot)millipore.com), ProQinase GmbH (worldwide website www(dot)proqinase.de) and others. All kinase assays were performed in 96-well FlashPlates from Perkin Elmer/NEN (Boston, Mass., USA) in a 50ul reaction volume. The reaction mixture was pipetted in four steps in the following order: 20ul of assay buffer (standard buffer),5ul of ATP solution (in H2O, 5 ul of test compound (in 10% DMSO), 10ul of substrate/10ul of enzyme solution (premixed)The assay for all enzymes contained 60 mM HEPES-NaOH (pH 7.5), 3 mM MgCl2, 3 mM MnCl2, 3uM Na-Orthovanadate, 1.2 mM DTT, 50 ug/ml PEG2000, 1 uM [33P]-ATP (approx. 5x1005 cpm per well).
