Chromatography Summary: | Reversed-phase analysis was performed on a Waters Ultra Performance liquid chromatography Acquity I-Class system using an Acquity HSS T3 2.10 x 100 mm column (Waters, Milford, USA). The column was maintained at 55 °C. The lipid extracts were analyzed by UPLC-MSE by injecting 10 μl of each sample dissolved in 1 mL of water:acetonitrile:2-propanol (H2O:ACN:2-propanol; 1:1:2, v:v:v) (Merck, Darmstadt, Germany). The chromatographic run was carried out in gradient mode with a flow rate of 0.5 mL min-1 with initial composition of 50% solvent B (ACN:2-propanol; 10:90) in solvent A (H2O:ACN; 40:60, v:v + 10 mM ammonium acetate (NH4Ac) (Sigma-Aldrich, Saint Louis, USA), maintained for 0 to 0.5 min. The gradient composition was changed linearly from 50% to 100% solvent B between 0.5 to 4.5 minutes, returning to the initial composition of 50% B in 4.6 minutes, kept to 5.0 minutes. |
