| Description: | 10 mM test compound stock or 1 mM control compound stock (tofocitinib, ruxolitinib or staurosporine) in DMSO was diluted to 0.4 mM in DMSO. A 3-fold series dilution was then performed in DMSO to generate 10 different compound concentrations. The assay was carried out in 384-well white plate. 0.5 uL of 40× compound DMSO solution at different concentrations was mixed with 10 uL 2× enzyme prepared in reaction buffer (20 mM HEPES, 10 mM MgCl2, 0.01% Tween, 1 mM DTT, pH 7.5). 10 uL 2× substrate mixture prepared in reaction buffer was then added to start the reaction. A short spin was done to settle down all solutions to the bottom of the plate. Final concentrations of test compound in the reaction mixture were 10000, 3333, 1111, 370, 123, 41.2, 13.7, 4.57, 1.52 and 0.51 nM. Concentrations of control compound were ten times less. Enzymatic reaction was conducted at 25° C. for 1-2 hours. 10 uL of Kinase Glo Reagents was added to stop the reaction and generate the luminescent signal which was measured using Envision. |
