| Description: | 1. The substrate was prepared in freshly prepared reaction buffer;2. The required cofactor was added to the above-mentioned substrate solution;3. The kinase BTKC481S sis was added to the above-mentioned substrate solution and mix well;4. The compound dissolved in DMSO was added to the kinase reaction mixture through Echo550 (Acoustic technology; nanolite range), and the mixture was incubated at room temperature for 20 minutes;5. 33P-ATP (specific activity of radioactivity is 10 μCi/μL) was added to the reaction mixture to initiate the reaction;6. The mixture was incubated at room temperature for 2 hours;7. The radioactivity was detected by filter-binding method;8. Kinase activity data represented the percentage of remaining kinase activity in the assay sample compared to the vehicle (dimethyl sulfoxide) reaction. IC50 value and fitted curve were obtained using Prism (GraphPad software). |
