| Description: | Caliper ABL1 (64-515) Assay: The assay plates were prepared by addition of 50 nL per well of compound solution in 90% DMSO. The kinase reactions were started by stepwise addition of 4.5 μL per well of peptide/ATP-solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 μM sodium orthovanadate, 20 mM MgCl2, 2 mM MnCl2, 4 μM ATP, 4 μM peptide (FITC-Ahx-EAIYAAPFAKKK-NH2)) and 4.5 μL per well of enzyme solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 μM sodium orthovanadate, 20 mM MgCl2, 2 mM MnCl2, 3.5 nM ABL (ABL(64-515), produced in-house from E. coli)). Kinase reactions were incubated at 30° C. for 60 minutes and subsequently terminated by addition of 16 μL per well of stop solution (100 mM HEPES pH 7.5, 5% DMSO, 0.1% Caliper coating reagent, 10 mM EDTA, and 0.015% Brij35). Plates with terminated kinase reactions were transferred to the Caliper LC3000 workstations for reading. Phosphorylated and unphosphorylated peptides were separated using the Caliper microfluidic mobility shift technology. |
