Sample Preparation:

Sampleprep ID:	SP002981
Sampleprep Summary:	For metabolite extraction, media was aspirated and cells were washed with cold 150mM ammonium acetate pH 7.3. Metabolite extractions were performed by adding 500μl of cold 80% methanol containing 2nM Norvaline (Sigma) as an internal standard per well. Cells were removed using a cell scraper before transferring cell suspensions to 1.5ml Eppendorf tubes. Samples were vortexed for 30 seconds and spun at 4°C for 5 minutes at maximum speed to pellet the insoluble fraction before 420 µl of the soluble fraction was transferred to ABC vials (Thermo Fisher Scientific). 80% MeOH was evaporated from the ABC vials using the EZ-2Elite evaporator (Genevac) and samples were stored at -80°C until analysis.
