Sampleprep Summary: | A pool of 2 frozen stool samples from 2 independent mice (total dry weigh 15-25mg) from the different experimental groups [UN-Acute n=5; UN-Chronic n= 7; DSS-acute, at the end (n=5) or one week after DSS treatment (n=5) and DSS-chronic (n=8)] were mixed and shacked for two times in 750 l of aqueous solution with 75% of methanol, 0.1% of formic acid and 1ug/ml of formonetin as internal control for 20 min at room temperature. The mixture was then vortexed for 3 min followed by centrifugation at 15 000g for 15 min. The suspension (600μL) was used for metabolic profiling. For the LC-ESI-MS analysis, samples were transferred to HPLC tubes and an aliquot of 3 μL was injected for the analysis. Liquid chromatography coupled to high-resolution mass spectrometry conditions were as pre-viously reported https://www.mdpi.com/1422-0067/22/18/9716. |
