| Description: | TBK1 inhibition is determined using a 384 well μlate format in buffer containing 20 mM Hepes, pH 7.4, 10 mM MgCl2, 1 mM EDTA, 0.01% Brij-L23, 1 mM DTT. Each test compound is prepared in DMSO using 2.5-fold serial dilutions for 11 data points, which are added to the buffer so that each dilution contains 1% DMSO. To each well is added 2 μL of 1 μM 5FAM-DRHDSGLDSMKDE-NH2 (in buffer), 2 μL of diluted test compound (1% DMSO in buffer), and 5 μL of 3 nM TBK1 and 25 μM ATP (in buffer). The reaction mixture is incubated at RT for 60 min, and quenched by adding 20 mM Hepes, pH 7.4, 10 mM MgCl2, 1 mM EDTA, 0.01% Brij-L23, 1 mM DTT+25 mM EDTA. To quantify the fluorescent-labeled substrate and product following reaction, the test plate is loaded on a Caliper LC-3000, which measures percent of conversion by microfluidic-based separation. |
