| Description: | 1. Preparation of test reagents {circle around (1)} 1x kinase buffer (50 mM HEPES, pH 7.5, 10 mM MgCl2, 1 mM EGTA, 3 mM MnCl, 0.01% Tween-20, 2 mM DTT); {circle around (2)} 4x kinase solution (added mTOR kinase to 1x kinase buffer to provide 4x kinase solution with a final concentration of 2.5 nM); {circle around (3)} 2x substrate solution (added the substrates of 4EBP1 and ATP into 1x kinase buffer to provide 2x substrate solution with 4EBP1 final concentration of 50 nM and ATP final concentration of 10.8 uM); {circle around (4)} 4x test substance solutions (100x test substance solutions with different concentration gradients were prepared using 100% DMSO, and diluted 25-fold with 1x kinase buffer to give 4x test substance solutions with different concentration gradients) {circle around (5)} preparation of test solution (test solution containing EDTA and 4EBP1 phosphorylated antibody was prepared using activity test kit with assay buffer, the final concentration of EDTA was 8 mM, and the final concentration of 4EBP1 phosphorylated antibody was 2 nM) 2. 2.5 uL of 4x test solution was added to a 384-well plate in parallel; 3. added 2.54 uL of 4x kinase solution and incubated for 10 min; 4. then added 5 uL of 2x solutions of 4EBP1 and ATP substrates and incubated for 1 h at room temperature; 5. finally, added 10 uL of test solution to quench the reaction, and read after 60 min; 6. IC50 value was obtained via curve fitting. |
