Sample Preparation:
Sampleprep ID: | SP001590 |
Sampleprep Summary: | Frozen liver pieces weighting ~30mg were transferred into soft tissue homogenizing CK 14 tubes containing 1.4 mm ceramic beads (Bertin corp.) prefilled with 1 ml of cold (-20°C) metabolites extraction solvent (Methanol: Acetonitrile:H2O, 50:30:20) and kept on ice. Samples were homogenized using precellys 24 tissue homogenizer (3X20sec at 6000 rpm, with a 30sec gap between each of the three cycles, Bertin Technologies) cooled to 2°C. Homogenized extracts were centrifuged in the Precellys tubes at 18,000g for 15 minutes at 4°C, supernatants were collected in microcentrifuge tubes and centrifuged again at 18,000g for 10 minutes at 4°C. The supernatants were transferred to glass HPLC vials and kept at -75 °C prior to LC-MS analysis. |
