Sampleprep Summary: | Cells were seeded in 6-well plates and collected the following day at 70% confluency. Cells were washed at room temperature with PBS twice and then kept on cold bath with dry ice and methanol. Metabolite extraction solution (50% methanol, 30% acetonitrile, 20% ultrapure water, 5 µM final concentration valine-d8) was added to each well following the proportion of 0.5 ml of extraction solution per million cells. The extracts were scraped and mixed at 4°C for 15 min. After final centrifugation at max speed for 15 min at 4°C, the supernatants were transferred into LC-MS vials. |
