| Description: | All reactions took place in 60 μL volumes in reaction buffer containing 40 mM Tris-HCl and 20 mM magnesium chloride, supplemented with 0.1 mg/mL bovine serum albumin and 2 mM DTT. Compounds were serially diluted in buffer and 5 μL of each concentration pipetted into a white 384 well plate (Sigma Aldrich M6186). A 5 μL aliquot of the Wee-1 enzyme was added to each well and the plate centrifuged for 1 min to ensure mixing of the enzyme and inhibitor. The plate was incubated at room temperature for 30 minutes before the addition of 2.0 μg/mL of substrate and 30 μM ATP in a 5 μL aliquot. The plate was centrifuged for one minute and incubated for 1 h at RT. 15 μL of ADP-Glo stop reagent was added to each well to quench the reaction and deplete unconverted ATP. The plate was incubated for a further 40 min in the dark at RT. 30 μL of ADP-Glo kinase detection reagent was added to each well, converting ADP to ATP, catalysing the generation of luciferin by luciferase. The plate was shaken for 1 min, and incubated in the dark for an additional hour. |
