Sample Preparation:

Sampleprep ID:	SP002047
Sampleprep Summary:	To extract metabolites, 40~50mg snap-frozen samples were completely homogenized by Shake Master NEO (Bio Medical Science) in 500uL of methanol containing L-methionine sulfone (Wako 502-76641), methionine sulfone (MES, Dojindo 349-01623), and D-camphor-10-sulfonic acid sodium salt (CSA, Wako 037-01032) (all at 20 μM). After adding CHCl3 (500 μl) and distilled water (200 μl) with thorough mixing, centrifugation was performed at 4,600g for 15 min at 4°C. Then the aqueous layer (300 μl) was collected and transferred to a 5-kDa cutoff filter (UltrafreeMC-PLHCC; Human Metabolome Technologies, UFC3LCCNB-HMT). Centrifugation was performed at 9,100g for 3 hours at 20°C, after which the filtrate was centrifugally concentrated and dissolved in 50μl distilled water containing reference compounds (200 μM each of 3-aminopyrrolidine and trimesate).
