Sample Preparation:

Sampleprep ID:	SP002147
Sampleprep Summary:	Prior to LC-MS analysis, tissue samples were weighed and resuspended in pre-chilled (-20°C) methanol:acetonitrile:water (5:3:2, v:v) to a final concentration of 30 mg/ml, cell samples were placed on ice and re-suspended with methanol:acetonitrile:water (5:3:2, v:v) at a concentration of 2x106 cells/mL, and media samples were extracted with the same solution at a dilution of 1:25 (v/v). Suspensions were vortexed continuously for 30 min at 4°C. Insoluble material was removed by centrifugation at 18,000 g for 10 min at 4°C and supernatants were isolated for metabolomics analysis by UHPLC-MS.
