| | Protein Kinase Assay Condition A (Thiol Containing Conditions) |
| Description: | A radiometric protein kinase assay (33PanQinase Activity Assay) was used for measuring the kinase activity of the three protein kinases. All kinase assays were performed in 96-well FlashPlates™ from PerkinElmer (Boston, Mass., USA) in a 50 μl reaction volume. The reaction cocktail was pipetted in four steps in the following order:20 μl of assay buffer (standard buffer)5 μl of ATP solution (in H2O)5 μl of test compound (in 10% DMSO)20 μl enzyme/substrate mixThe assay for all protein kinases contained 70 mM HEPES-NaOH pH 7.5, 3 mM MgCl2, 3 mM MnCl2, 3 μM Na-orthovanadate, 1.2 mM DTT, 50 μg/ml PEG20000, ATP (variable concentrations, corresponding to the apparent ATP-Km of the respective kinase), [γ-33P]-ATP (approx. 9×1005 cpm per well), protein kinase (variable amounts), and substrate (variable amounts). |
