| Description: | Assay #1:Inhibition of FAS activity can be measured based on the detection of residual NADPH substrate after the FAS assay is quenched. This assay is run as a 10 uL endpoint assay in 384-well format, where the reaction contains 20 uM malonyl-CoA, 2 uM acetyl-CoA, 30 uM NADPH and 40 nM FAS in 50 mM sodium phosphate, pH 7.0. The assay is run by sequentially dispensing 5 ul of a malonyl-CoA solution, then enzyme solution (containing the acetyl-CoA, and NADPH) into a black, low volume assay plate (Greiner 784076) pre-dispensed with 100 nL compound solutions in DMSO. The reaction is incubated at ambient temperature for 60 minutes, then quenched with 5 uL of a developing solution composed of 90 uM resazurin, 0.3 IU/ml diaphorase in 50 mM sodium phosphate, pH 7.0. The developed reaction is read on a Molecular Devices Analyst or Acquest (or equivalent) plate reader using a 530 nm excitation wavelength filter, a 580 nm emission filter, and 561 nm dichroic filter. |
