Sample Preparation:

Sampleprep ID:	SP002468
Sampleprep Summary:	For measurement of extracellular metabolome, 625 µL of media was added to 375 µL acetonitrile ACN. Samples were stored at -20 °C for at least two hours followed by centrifugation at 14,000xg to precipitate any proteins. 250 µL of the supernatant was mixed with 250 µL of water and added to a 3 kDa molecular weight cut-off filter spin column (Microcon YM-3 Centrifugal Filter, Millipore). Samples were centrifuged at 14,000xg at 4 °C for 30 min. The flow-through was saved for LC-MS/MS analysis.
