| Description: | Kinase base buffer (50 mM HEPES, pH 7.5 0.0015% Brij-35; 10 mM MgCl2 2 mM DTT) and Stop buffer, (100 mM HEPES, pH 7.5 0.015% Brij-35; 0.2% Coating Reagent (50 mM EDTA) are prepared. Test compound is diluted in 100% DMSO to 50-times the desired final inhibitor concentration (the Stock Solution) and serially diluted in half-log increments resulting in final concentrations 250 μM to 75 μM, 25 μM, 7.5 μM, 2.5 μM, 0.75 μM, 0.25 μM, 75 nM, 25 nM, 7.5 nM in DMSO. 10 μl of each compound is placed in a 96-well plate as the intermediate plate. 90 μl of Kinase Buffer is added to to each well to prepare the intermediate plate.Figure US10906896-20210202-P00001Mix the compounds in intermediate plate for 10 min on shaker. For the assay of enzyme inhibitions, 5 μl of each well from the intermediate plate is transferred to a 384-well plate in duplicates, 10. Then 10 μl of 2.5× enzyme solution is added to each well of the 384-well assay plate and incubated for 10 min. Then enzyme substrate is added as 10 μl of 2.5×FAM-labeled peptide+ATP solution to each well of the 384-well assay plate. The reaction is allowed to proceed at 28° C. and quenched with the addition of 25 μl of stop buffer. |
