| Description: | Assays were conducted in a volume of 76 μl assay buffer (150 mM NaCl, 10 mM MgCl2, 20 mM Tris pH 7.5, 0.03% bovine serum albumin) as follows in a standard 384-well plate: To 25 ul of substrate mix (8 uM NADPH, 2 mM aKG), 1 μl of test compound was added in DMSO. The plate was centrifuged briefly, and then 25 μl of enzyme mix was added (0.2 μg/ml IDH1 R132H) followed by a brief centrifugation and shake at 100 RPM. The reaction was incubated for 50 minutes at room temperature, then 25 μl of detection mix (30 μM resazurin, 36 μg/ml) was added and the mixture further incubated for 5 minutes at room temperature. The conversion of resazurin to resorufin was detected by fluorescent spectroscopy at Ex544 Em590 c/o 590. |
