Sample Preparation:

Sampleprep ID:	SP002329
Sampleprep Summary:	Mouse cortical lysate samples were rapidly isolated, and flash frozen in liquid nitrogen. Soluble metabolites were extracted directly from tissue using cold methanol/water (80/20, v/v) at approximately 1μL per 50μg of tissue, followed by ultrasonication (Branson Sonifier 250) for 15 s. Homogenized samples were incubated at −80 °C to precipitate proteins and subsequently centrifuged at 18,000xg for 20 min at 4 °C to pellet the debris. The supernatants containing soluble metabolites were collected in new tubes and evaporated to dryness using a SpeedVac concentrator (Thermo Savant). Next, the metabolites were reconstituted in acetonitrile/water (60/40, v/v), vortex-mixed, and centrifuged at 18,000xg for 30 min at 4°C to remove debris.
