Study ID	ST001167
Study Title	Comprehensive Profiling by Non-targeted Stable Isotope Tracing Capillary Electrophoresis-Mass Spectrometry
Study Summary	We developed a stable-isotope tracing capillary electrophoresis (CE)-MS metabolomics approach to cover polar metabolites as well as isotopologues in a non-targeted way. An in-house developed software enables high throughput processing of complex multi-dimensional data. The practicability is demonstrated analysing 13C-U-glucose exposed prostate cancer and non-cancer cells.

Sample Preparation:

Sampleprep ID:	SP001240
Sampleprep Summary:	After the cultures have been grown for the targeted amount of time, the medium was aspirated completely, then cells were washed thrice with 5% D-mannitol solution, followed by inactivation with liquid nitrogen immediately. Cells were handled on ice during the preparation. 1 mL of precooled methanol, containing 13.3 μM of MetS and CSA, was added to each cell culture dish. Cells were harvested using a cell scraper, and transferred into a 5 mL tube. Then, 1 mL of chloroform was added and vortexed for 5 min, followed by 400 μL of Milli-Q water and 10 min of vortexing. After 5 min of standing, the mixture was centrifuged to form a two-phase system (10,000 g, 4 °C, 15 min). The upper layer was transferred and centrifugally filtered through a Millipore 5-kDa cutoff filter (USA) (13,000 g, 3h at 4°C). The filtrate was dried and stored at -80 °C. Finally, the upper extract was dissolved in Milli-Q water containing 50 μM of 3-AP, DPA, DHD and TMA for capillary electrophoresis-time of flight mass spectrometry (CE-TOF/MS) analysis.
