Study IDST001367
Study TitleMalnutrition and Liver Metabolomics Pre-Intervention (part-I)
Study SummaryRP-UPLC-FTMS (+/- ion detection) and HILIC-FTMS (+/- ion detection) were conducted on murine livers from healthy (CON) and malnourished (MAL) mice. To examine the impact of gut microbes and malnutrition, data was also collected from a third group (MBG).

Sample Preparation:

Sampleprep ID:SP001449
Sampleprep Summary:RP-UPLC-FTMS: Individual mouse liver samples were mixed with water, 5 μL per mg of the tissue, and two 4-mm metal balls were added to an Eppendorf tube. The tissue was homogenized on a MM 400 mill mixer at a vibrating frequency of 30 Hz for 1 min twice. After 5-s spin-down, a mixture of methanol-chloroform (4:1) was added, at 25 μL per mg tissue, to each tube. The sample was homogenized again for metabolite extraction using the same setup for 1 min twice, followed by sonication in an ice-water bath for 5 min. The tube was centrifuged at 15,000 rpm and at 10 0C for 20 min. The clear supernatant was transferred to a 1.5-mL Eppendorf tube. A 60-μL aliquot from each sample was dried down inside the same nitrogen evaporator and the residue was reconstituted in 40 μL of 80% methanol. 10 μL was injected for reversed-phase RP-UPLC-FTMS. HILIC-FTMS: Individual sample supernatants were mixed with 120 μL of water, 180 μL of methanol and 195 μL of chloroform. The mixture was vortex mixed at 3000 rpm for 30 s before centrifugal clarification. 300 μL of the upper, aqueous phase was precisely taken out and transferred to a “V”-shape LC injection microvial and was dried down under a gentle nitrogen gas flow in the nitrogen evaporator. The residue was reconstituted in 50 μL of 80% acetonitrile. 10 μL was injected for HILIC-FTMS. *See Methods
