| Description: | CDK4: The test compound was dissolved in DMSO and diluted with a kinase buffer solution (20 mM HEPES-pH 7.5, 0.01% Triton X-100, 10 mM MgCl2, 2 mM DTT) and 5 μL of compound at 5-fold final concentration of reaction dissolved in 10% DMSO was added in a 384-well plate. The compound-free control well was 5 μL of 10% DMSO, and the no-activity control well was 5 μL of kinase buffer. 10 μL of a 2.5-fold diluted CDK4 enzyme solution (GST-CDK4(1-303 end)) was added and incubated at room temperature for 10 min, and then 10 μL of the 2.5-fold diluted substrate solution Peptide FAM-P8 was added. The reaction was stopped by adding 25 μL of stop solution after incubation at 28° C. for 3 h, and the conversion rate data was read on a Caliper EZ Reader II (Caliper Life Sciences) and the conversion rate was converted to inhibition rate data according to above method. |
