Sampleprep Summary: | For GC-MS analysis samples, 200 µL of frozen plasma supernatant was thawed at room temperature and 30 µL of 80 mg/L deuterated palmitic acid in MeOH was added as internal standard (IS). After samples were evaporated to dryness a two-step derivatization process was done. For CE-MS analysis, 200 µL of frozen supernatant was thawed until room temperature and it was evaporated to dryness using a SpeedVac Concentrator System (Thermo Fisher Scientific, MA). Afterwards, 100 µL of 0.2 mM methionine sulfone (MetS) as internal standard (IS) in 0.1 M formic acid solution was added. Samples were vortex mixed, filtered and subsequently centrifuged.
