| Description: | The substrate was prepared in base reaction buffer (20 mM Hepes (pH 7.5), 10 mM MgCl2, 1 mM EGTA, 0.02% Brij35, 0.02 mg/ml BSA, 0.1 mM Na3VO4, 2 mM DTT, 1% DMSO), and required cofactors were added to the substrate solution. The mTor kinase was delivered into the substrate solution, and the solution was gently mixed. Testing compounds were dissolved in 100% DMSO to specific concentration. The serial dilution was conducted by Integra Viaflo Assist in DMSO. The compounds were delivered into the kinase reaction mixture by Acoustic technology (Echo550; nanoliter range), and the reaction mixture was incubated for 20 min at room temperature. Then, 33P-ATP (Specific activity 10 μCi/μl) was delivered into the reaction mixture to initiate the reaction. The reaction mixture was incubated for 2 hours at room temperature. Radioactivity was detected by a filter-binding method. Kinase activity data were expressed as the percent remaining kinase activity in test samples compared to vehicle (dimethyl sulfoxide) reactions. IC50 values and curve fits were obtained using Prism (GraphPad Software). |
