| Description: | The assay was performed in a final volume of 6 μL in assay buffer containing 50 mM Hepes (pH 7.5, (0.5M Hepes, pH 7.5 solution; Teknova H1575)), 0.5 mM GSH, 0.01% BGG (0.22 p M filtered, Sigma, G7516-25G), 0.005% BSA (0.22 μM filtered, EMD Millipore Corporation, 126575) and 0.01% Triton X-100 (Sigma, T9284-10L). Nanoliter quantities of 10-point, 3-fold serial dilution in DMSO were pre-dispensed into 1536 assay plates (Corning, #3724BC) for a final test concentration of 33 μM to 1.7 nM, top to lowest dose, respectively. 3 μL of 2×Protein and 3 μL of 2×Peptide Ligand were added to assay plates (pre-stamped with compound). Plates were incubated for varying times at room temperature prior to measuring the signal. TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) was measured on the PHERAstar (BMG, equipped with HTRF optic module [337/520/490]) or on the Envision (PerkinElmer, equipped with the TRF Laser unit, TRF dual mirror D400/D505 and emission filters M520 and M495). |
