Study TitleComprehensive Profiling by Non-targeted Stable Isotope Tracing Capillary Electrophoresis-Mass Spectrometry
Study SummaryWe 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.

Collection ID:CO001226
Collection Summary:cells were grown in RPMI 1640 medium containing 2 g/L glucose with 10% dFBS, and were harvested at 80% confluence. One hour before the isotope switch, the medium was aspirated and replaced with fresh unlabeled medium[1]. Subsequently, VCaP and RWPE-1 were cultured in RPMI 1640 medium with 2 g/L [U−13C]-glucose and 10% dFBS for 0 h, 0.25 h, 4 h, 12 h, 24 h and long-term for 6 days performing thereby 3 passages. 10 cm petri dish with 10 mL of media was used for each sample, and 4 independent biological replicates were prepared for the labeling experiments. Unlabeled samples were treated in the same way with medium containing unlabeled glucose. 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.
