Sample Preparation:

Sampleprep ID:	SP002484
Sampleprep Summary:	Subsequently, cell culture supernatant was stored for profiling the extracellular metabolome. Three replicates per cell line and blanks were washed with 0.9% NaCl and quenched with ice-cold methanol and ice-cold ddH2O (containing 1 µg/ml D6-glutaric acid as internal standard). Cells were scraped and extracts were added into tubes containing ice-cold chloroform. Following vortexing at 1,400 rpm for 20 min at 4°C and centrifugation at 17,000 g for 5 min at 4°C, 300 µl of the polar phase were transferred into GC glass vials with microinsert and dried under vacuum at 4°C. Dried extracts were derivatized using equal amounts of methoxylamine (20 mg/ml in pyridine) and MTBSTFA.
