Chromatography Summary: | Lipids were identified and quantitatively measured using ultra high-performance liquid-chromatography high-resolution tandem MS/MS (UHPLC-MS/MS) as recently described89,90. Separation of lipids was done by reverse-phase chromatography using a Waters ACQUITY CSH C18 column (150x2.1mm; 1.7um) at 60°C using a Vanquish UHPLC system (Thermo Scientific) and two solvents: solvent A (40:60 water-methanol plus 10mM ammonium formate and 0.1% formic acid) and solvent B (10:90 methanol-isopropanol plus 10mM ammonium formate and 0.1% formic acid). UHPLC was performed at a 0.25 ml per min flow rate for 30 min per sample, starting at 25% solvent B and ending at 100% solvent B as described. The column was washed and equilibrated between samples. Samples were run in a semi-random order where WT or UBXD8 KO samples were interspersed with blank samples. Each sample was repeatedly analyzed using various injection volumes (4, 8, 16ul for positive mode and 5, 10, and 15ul for negative mode). |
