| Description: | An assay buffer containing GCN2 kinase and (RS)7 was prepared. 4.7 μL of this stock solution was placed per well of a black, low volume, 384-well microtitre plate (e.g. catalogue number 3676, Corning Inc., NY). To this was added 0.65 μM of DMSO containing serial dilutions of the test compound (typical final concentrations of test compound were 0 to 8 μM). The plate was incubated for 10 minutes at 25° C. prior to the addition of 4.7 μL of ATP stock buffer to initiate the enzyme reaction. The reaction was allowed to proceed for 1 hour at 25° C., prior to the addition of 10 μL detection buffer (consisting of appropriate concentrations of ADP2 antibody and ADP Alexa633 tracer in 1× stop and detect buffer as supplied by BellBrook Labs). The reaction was left to incubate for 1 hour at 25° C., prior to measuring the fluorescence polarisation signal (mP) in each well using a PHERAstar FS reader (BMG Labtech, Germany). |
