| Description: | IRAK4 kinase (purchased from Life Technologies, Cat. No.: PR5612U) was diluted to 2 folds of the final concentration (the final concentration is 0.76 ng/4) with reaction buffer (40 mM Tris-HC1, pH 7.5; 20 mM MgCl2; 0.1 mg/mL BSA; 1 mM DTT), and added to a 384-well plate at 5 μL/well. The test drugs were 10-fold serial diluted from 10 μM to set six concentration points and added to the test wells of the 384-well plate at 2.5 μL/well. After incubation for 10 min at 25° C., 10 μM of ATP and 0.1 μg/μL of an enzyme reaction substrate, myelin basic protein MBP (purchased from Signal Chem, Cat. No.: M42-51N) were added at 2.5 μL/well, and reacted at 25° C. for 60 minutes. After the reaction was completed, the kinase activity assay was performed using the ADP-Glo kinase assay kit (purchased from Promega, Cat. No.: V9102) according to the manufacture's instruction, i.e., 10 μL of ADP-Glo reaction reagent was first added and reacted at 25° C. for 40 minutes, 10 μL of the reaction mixture was taken and mixed with 10 μL of ADP-Glo detection reagent, and reacted at 25° C. for 30 minutes. |
