| Sampleprep Summary: | 50 mg of sample was taken and placed in an Eppendorf tube, followed by the addition of 1000 µl extraction solvent containing an internal target (V methanol : V acetonitrile : V water = 2 : 2 : 1, containing internal standard 2 µg/ml). The mixture was homogenized in ball mill for 4 min at 45 Hz, then ultrasound treated for 5min (incubated in ice water). After homogenization for 3 times, the mixture was incubated for 1 h at -20 °C to precipitate proteins. Centrifugation was performed at 12000 rpm for 15 min at 4 °C. A total of 825 µl supernatant was carefully transferred into a fresh Eppendorf tube, and dried in a vacuum concentrator without heating. 200 µl extraction solvent (V acetonitrile: V water = 1:1) was then added for reconstitution, followed by vortex 30 s and sonicated for 10 min (4 °C water bath), centrifuge for 15 min at 12000 rpm (4 °C). 75 µl supernatant was transferred into a fresh 2 ml LC/MS glass vial for UHPLC-QTOF-MS analysis, while another 20 µl was taken from each sample and pooled as QC samples. Six technical replicates were conducted to QC sample with 75 µL each for UHPLC-QTOF-MS analysis. |
