| Description: | Experimental Reagents:Basic reaction buffer: 20 mM hydroxyethylpiperazine ethanesulfuric acid (pH 7.5), 10 mM magnesium chloride, 1 mM EGTA, 0.02% Brij35, 0.02 mg/mL bovine serum albumin, 0.1 mM Na3VO4, 2 mM DTT, 1% DMSOEnzyme: Wee-1 concentration is 150 nMMatrix: MBP concentration is 20 μMCompound Treatment:The tested compound was formulated into a 5 mM solution with 100% DMSO, and a 10 points 3-fold gradient dilution was performed with DMSO through an automated pipetting station epMotion 5070.Experiment Procedure:1. Fresh matrix configuration reaction buffer was prepared;2. The Wee-1 was added into the matrix solution and shaked gently;3. DMSO solution of the compound were added into the kinase reaction mixture using an acoustic technique (Echo 550; nanoliter range) and incubated for 20 minutes at room temperature;4. 33P-ATP (specific activity, 10 μCi/μL) was added into the reaction mixture to stimulate the reaction;5. Incubated for 2 hours at room temperature;6. Kinase activity was detected by filter-binding method. |
