| Description: | The SCD1 enzymatic assay was done in a volume of 50 μL using 10 μg of RLM (prepared as described above) in a 96-well polypropylene plate (enzyme reaction buffer contains 0.1 M K-Phosphate Buffer, 10 mM ATP, 6 mM MgCl2. 1 mM CoA, 1 mM β-NADH, 1.6 mM L-glutathione, 20 μM Stearoyl-CoA). Stearoyl-[9,10-3H]-CoA (ARC-0390, 1 mCi/mL, 60 Ci/mmol,) was added at a final concentration of 2 μCi/mL. Test compound was then added to the reaction mixture at the selected concentration. After incubation at room temperature for 2 hours, 5 μL 1 N HCl was added to stop the reaction, followed by addition of 25 μL of 10% charcoal. The reaction mixture was then transferred to 96-well Multiscreen plate (Millipore, Cat#MSFCN6B50). [3H2O] was collected into Opti-plate (PE, Cat#6005290) by centrifuge, at 1,000 rpm for 2 minutes. 150 μL Microscint 40 (PE, cat #6013641) was then added to each well and counted on Topcount for [3H] counts per minute (cpm). |
