| Description: | Briefly, according to the requirements of different kinase reactions, 0.2 μL test compound (50 μM, dissolved in dimethyl sulfoxide (DMSO)) is added to reaction buffer containing specific kinase (the buffer system containing 20 mM MOPS, 1 mM EDTA, 0.01% Brij-35, 5% Glycerol, 0.1% β-mercaptoethanol, 1 mg/mL BSA, or 50 mM TRIS, 0.1 mM EGTA, 0.1 mM Na3VO4, 0.1% β-mercaptoethanol, 1 mg/mL BSA, based on the type of kinase used). Subsequently, a kinase specific substrate at a final concentration of 50 μM (specific substrate used for specific kinase), 10 mM Mg Acetate and isotope-labeled γ-33P ATP (radio-activity of about 500 cpm/pmol) are sequentially added to a total volume of 10 μL for the reaction system. After incubation at room temperature for 40 min, the reaction is terminated by adding 3% phosphoric acid solution. The mixture is then transferred to a filter-type low temperature spray dryer (P30 filtermat), and washed by 75 mM phosphoric acid solution for 3 times and by methanol once. After drying, radio-activity is detected. |
