| Description: | Experimental Methods:(1) Prepare a 1× kinase buffer [50 mM 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES), PH 7.5, 0.01% Brij-35, 10 mM MgCl2, 2 mM dithiothreitol (DTT)].(2) Prepare compound:The testing compound was dissolved with DMSO. The testing compound was diluted up to 100× final concentration in a 384-well plate. Transfer 250 nL of the compound dilution to a 384-well assay plate using Echo 550. 100% DMSO of 250 nL was added to the negative control well and the positive control well.(3) Prepare a 2.5× enzyme solution using the above 1× kinase buffer.(4) Add 10 μL of the 2.5× enzyme solution to the compound well and the positive control well of the 384-well assay plate. Add 10 μL of the 1× kinase buffer to the negative control well.(5) The 384-well plate was centrifuged at 1000 rpm for 30 seconds and incubated at room temperature for 10 min.(6) A mixture of ATP and Kinase substrate 21 with a final concentration of 25/15× was prepared by the 1× kinase buffer.(7) Add 15 μL of the mixture of 25/15×ATP and kinase substrate solution 21 to start reaction.(8) The 384-well plate was centrifuged at 1000 rpm for 30 seconds and incubated at room temperature.(9) 30 μL of the stop and detection buffer was added to stop the kinase reaction and centrifuged at 1000 rpm for 30 seconds.(10) Collect data on Caliper EZ ReaderII.Data Analysis: |
