| Description: | Detection of Myt1 kinase activity utilized a recombinant human Myt1 kinase assay measuring the hydrolysis of ATP using a commercially available ADP-Glo Assay (ADP-Glo Kinase Assay from Promega, 10 000 assays, #V9102). Briefly, 5 μL recombinant human Myt1 (full length PKMYT1 recombinant human protein expressed in insect cells from Thermo Fisher #A33387; 80% purity) was prepared in reaction buffer (70 mM HEPES, 3 mM MgCl2, 3 mM MnCl2, 50 μg/ml PEG 20000, 3 μM Na-orthovanadate, 1.2 mM DTT) and added to 384 well white polystyrene, flat bottom well, non-treated, microplate (Corning #3572). After this, 5 μL of compounds (diluted in reaction buffer to 0.5% DMSO) was added to the microplate and the plate was spun briefly and incubated at 22 C. for 15 minutes. Ultra-Pure Adenosine Triphosphate (ATP) solution (ADP-Glo kit from Promega) was diluted in reaction buffer and 5 μL was added to the microplate, spun down briefly and incubated for 60 minutes at 30 C. The final Myt1 enzyme concentration was 18 nM and the final ATP concentration was 10 μM. After the 60-minute incubation, 15 μL of ADP-Glo reagent was added and the plate was spun briefly and sealed and incubated in the dark for 40 minutes at 22 C. Following this, 30 μL of kinase detection reagent was added per well and the plate was spun briefly, sealed and incubated for 45-60 minutes at 22 C. in the dark. Luminescence was read using the Envision (250 ms integration). T |
