"COLLECTION":{"COLLECTION_SUMMARY":"Mouse metabolites were collected from the liver of female mice using methanol extraction. After euthanizing a mouse, the liver was immediately frozen in liquid nitrogen. We then used cold 80% methanol to extract metabolites. First, 1 ml of 80% methanol was added to the liver and incubated for 10 min at -20oC. Glass beads were added to the liver and then the liver was lysed by bead-beating for 45 s using a Tissuelyser cell disrupter (Qiagen). The lysate was incubated for 10 min at -20oC and centrifuged (13200 rpm, 5 min) to separate metabolites from macromolecules. The supernatant was collected and 200 µl of 80% methanol was added to the pellet. The incubation, shaking and centrifugation steps were repeated twice to extract more metabolites from the pellet. The three supernatants were combined and centrifuged (14000 rpm, 10 min) to separate any remaining macromolecules from the metabolites. The combined supernatants were dried using a SpeedVac Concentrator (Savant, SPD131DDA) at 25oC and the dried metabolite samples were stored at -80oC.","SAMPLE_TYPE":"Liver","COLLECTION_METHOD":"80% methanol","STORAGE_CONDITIONS":"-80℃"},

"CHROMATOGRAPHY":{"CHROMATOGRAPHY_SUMMARY":"Chromatography of metabolites utilized reversed phase chromatography on a Agilent ZORBAX Eclipse Plus C18, 100 × 2.1 mm, 1.8 μm.
