Sample Preparation:

Sampleprep ID:SP002306
Sampleprep Summary:Metabolites from frozen cell pellets were extracted at 150,000 cells/mL in cold 5:3:2 MeOH:acetonitrile:water. Samples were vortexed 30 min at 4 degrees C then supernatants clarified by centrifugation (10 min, 10,000 g, 4 degrees C). Supernatants were split into two equal tubes and gently dried using a vacuum concentrator. One set of residues were resuspended in 12 uL of 0.1% formic acid (for positive ion mode). The other set of residues were resuspended in 12 uL of 1 mM ammonium acetate (for negative ion mode).
