Collection:
| Collection ID: | CO002103 |
| Collection Summary: | : Samples were taken before and after 6 weeks of flaxseed dietary intervention. Serum and fecal metabolomics were performed to characterize the metabolomic profiles of serum and stool metabolites pre- and post-intervention. |

Sample Preparation:
| Sampleprep ID: | SP002116 |
| Sampleprep Summary: | Extraction is carried out using a bi-phasic solvent system of cold methanol, methyl tert-butyl ether (MTBE), and water. In more detail, cold methanol (225 µL is added to a 5mg tissue sample aliquot, which is placed into a 1.5 mL Eppendorf tube. Then, 750 µL of cold MTBE is added, followed by vortexing for 10 s. and shaking for 6 min. at 4ºC. Phase separation is induced by adding 188 µL of mass spec-grade water. After vortexing for 20 s. the sample is centrifuged at 14,000 rpm for 2 min. The upper organic phase is collected in two 300 µL aliquots for lipid analysis polar layer is collected in two 125 µL aliquots for HILIC analysis. One is stored at -20ºC as a backup and the other is evaporated to dryness in a SpeedVac. Dried extracts are resuspended in acetonitrile. |
