| Study Title | Metabolic effect of the loss of mitochondrial-specific aspartyl-tRNA synthetase Das2 on mouse intestinal epithelial cells |
| Study Summary | We analysed the intestinal epithelial cell (IEC) from Dars2 fl/fl ; VillinCreERT2 tg/wt mice (n=15) and and Dars2 fl/fl ; VillinCreERT2 wt/wt mice (n=9) at 8 days upon tamoxifen injection to assess the metabolic effect of Das2 loss. Isolated IECs were divided into three technical replicates (n=69) and analysed with two analytical repeats (n=138). |

| Chromatography Summary: | LC-MS chromatographic separation of metabolites was achieved using a Millipore Sequant ZIC-pHILIC analytical column (5 µm, 2.1 × 150 mm) equipped with a 2.1 × 20 mm guard column (both 5 mm particle size) with a binary solvent system. Solvent A was 20 mM ammonium carbonate, 0.05% ammonium hydroxide; Solvent B was acetonitrile. The column oven and autosampler tray were held at 40°C and 4 °C, respectively. The chromatographic gradient was run at a flow rate of 0.200 mL/min as follows: 0–2 min: 80% B; 2-17 min: linear gradient from 80% B to 20% B; 17-17.1 min: linear gradient from 20% B to 80% B; 17.1-22.5 min: hold at 80% B. Samples were randomized and analysed with LC–MS in a blinded manner with an injection volume of 5 µl. Pooled samples were generated from an equal mixture of all individual samples and analysed interspersed at regular intervals within sample sequence as a quality control. |
