Sample Preparation:

Sampleprep ID:	SP003147
Sampleprep Summary:	For LC/MS-MS, 1000 μL of acetonitrile-methanol-H2O (2:2:1, containing isotope internal standards) was added to 50 mg samples. The samples were then homogenized, sonicated, and this process was repeated three times. After incubating the samples at -40 °C for 2 h, they were centrifuged at 12,000 rpm for 15 min at 4 °C. Subsequently, 800 μL of supernatant from each sample was transferred to a new EP tube and dried using a centrifugal concentrator. Next, 160 μL of 60% acetonitrile was added to reconstitute the dried samples. The mixture was vortexed for 30 s, and sonicated in an ice-water bath for 5 mins, followed by centrifugation at 12,000 rpm for 15 mins at 4 °C. Finally, 100 μL of supernatant from each sample was transferred into glass vials for LC-MS/MS analysis.
