Assay Method Information

Assay Name:  ATP Caliper Assay
Description:  Compounds were serially diluted in DMSO then further diluted in 1× kinase buffer: 5 uL of buffer diluted compound was added into wells first, then 10 uL of Tyk2 enzyme mix was added into wells, followed by 10 uL of substrate mix to start reaction. Reaction was incubated at 28° C. for 25 min and then added 25 uL stop buffer. The reaction mixture was read by a Caliper mass spectrometer. Final concentrations for assay conditions were: 25 mM HEPES, pH 7.5, 0.01% Brij-35, 0.01% Triton, 0.5 mM EGTA, 2 mM DTT, 10 mM MgCl2, TYK2 4 nM, ATP concentration 1000 uM, and P30 3 uM.
