Sample Preparation:

Sampleprep ID:SP002915
Sampleprep Summary:Serum samples from each mouse were thawed and 20 μL was consumed to extract metabolites for each mice. Metabolite extraction was facilitated by adding 180 μL methanol containing stable isotope-labeled chemicals ([D5]-glutamine, [D2]-𝛾-aminobutyric acid, [D3]-tryptophan, [D2]-indole-3-propionic acid, [D2]-indole-3-acetic acid, [D13]-acetylcholine in 500 nM; [D4]-serotonin in 250 nM; and [D4]-kynurenic acid in 50 nM), and incubated under -20°C for 1 hr, followed by centrifugation under 15,000 ×g, 4°C for 10 minutes to collect the supernatant (150 μL). The supernatant was dried by SpeedVac® and reconstituted with 100 μL 2% acetonitrile in water.
