Sample Preparation:
| Sampleprep ID: | SP001878 |
| Sampleprep Summary: | For lipidomics analysis, lipid was extracted from mesenteric lymph by chloroform:methanol (1:3). Samples were vortexed for 1 h at 4°C and then centrifuged at 16,000 g for 10 min. Supernatant was carefully transferred to another tube and stored at -80°C until analysis. Before LC-MS analysis, the extract was dried with nitrogen and reconstituted in 20 µl water and 180 µl butanol-methanol (1:1 v/v). The reconstituted extract was vortexed (Vortex mixer, Ratek) for 200 sec with 20 cycles of 5 sec spin and 20 sec vortex. The extract was sonicated in a water bath for 1 hour which was maintained at <20°C by sonicating the samples on ice. The samples were then centrifuged for 10 min at 16,000 g and the supernatant was transferred to LC-MS vials and stored at 4°C prior to analysis. |
