Chromatography Summary: | UHPLC-MS metabolomics analyses were performed using a Vanquish UHPLC system coupled online to a Q Exactive mass spectrometer (Thermo Fisher, Bremen, Germany). Samples were resolved over a Kinetex C18 column (2.1x150 mm, 1.7μm; Phenomenex, Torrance, CA, USA) at 25°C using a 3-minute isocratic flow rate at 250μL/minute at 0% B (A: 95% water/5% acetonitrile, 5mM NH4OAc) for positive mode. To monitor possible technical variability, aliquots of each of the individual samples were combined to make technical replicates, which were run after every 15 samples. Additionally, in each experiment, several lysis solution aliquots were run as blanks for artifact identification. The Q Exactive mass spectrometer (Thermo Fisher Scientific, San Jose, CA, USA) was operated in negative ion mode using electrospray ionization, scanning in Full MS mode (2μscans) from 65 to 900 m/z at 70,000 resolution, with 4 kV spray voltage, 15 sheath gas, 5 auxiliary gas. MS analysis and data elaboration were performed as described74,75. Calibration was performed prior to analysis using the PierceTM Negative Ion Calibration Solution (Thermo Fisher Scientific). |
