Sample Preparation:

Sampleprep ID:	SP002436
Sampleprep Summary:	Cell lysates (20 μL) were removed for a protein assay, and the remaining cell lysates were extracted by the addition of 4.5 mL of methanol containing 3 μg of internal standard (acetaminophen). The cells were completely collected with a cell scraper. Finally, the suspension of cell debris in each dish was transferred to an Eppendorf tube, vigorously vortexed for 5 min, and then centrifuged at 10,000×g for 10 min at 4 °C. The supernatant was transferred to another tube and evaporated to dryness in a Refrigerated CentriVap Benchtop Vacuum Concentrator (Labconco Corporation, Kansas City, MO). The pellets were reconstituted with methanol-water (75:25) and centrifuged twice at 12,000×g for 15 min at 4 °C.
