Sample Preparation:

Sampleprep ID:	SP001525
Sampleprep Summary:	P100 plasma was profiled using the Metabolon (Durham, USA) Global Metabolomics Platform, as described (2-4). Briefly, samples were extracted with methanol under vigorous shaking for two minutes (Glen Mills GenoGrinder 2000) followed by centrifugation to remove protein, dissociate small molecules bound to protein or trapped in the precipitated protein matrix, and to recover chemically diverse metabolites. The resulting extract was divided into five fractions: two for analysis by two separate reverse phase/ultrahigh performance liquid chromatography/tandem mass spectrometry (RP/UPLC-MS/MS) methods with positive ion mode electrospray ionization (ESI), one for analysis by RP/UPLC-MS/MS with negative ion mode ESI, one for analysis by hydrophilic interaction chromatography (HILIC)/UPLC-MS/MS with negative ion mode ESI, and one sample was reserved for backup.
