Sample Preparation:

Sampleprep ID:	SP002188
Sampleprep Summary:	100-130 mg liver tissue samples were weighted, 1.2 mL of 80% ice-cold aqueous methanol, which contains 0.001 mg/mL internal standard, and approximately 1 g of glass beads (1.0 mm i.d.) was added into a 2 mL screw-cap plastic microvial. The Mini-BeadBeater-16 (Biospec Products, USA) was used for tissue disruption. Samples were homogenized 3 times for 2 min each, with cooling procedure in between, centrifuged at 20,000 g for 10 min at 4 °C, and the supernatants were mixed with 800 μL of ice-cold acetonitrile and centrifuged again for protein precipitation. The supernatant was filtered through a 0.22 µm organic phase membrane, blown dry in nitrogen, reconstituted in 100 µL of water and transferred to vials for metabolomics assay.
