Collection:
| Collection ID: | CO002540 |
| Collection Summary: | Snap-frozen kidneys were transferred into 0.5 ml homogenization tubes prefilled with 1.4mm ceramic beads (CK14, # P000933-LYSK0-A, Bertin corp) and cold (-20°C) metabolites extraction solvent (Methanol: acetonitrile: water at a ratio of 5:3:2 respectively) |
| Sample Type: | Kidney |
Treatment:
| Treatment ID: | TR002559 |
| Treatment Summary: | A mixture of six labeled internal standards was added to the extraction solution for quality control (13C6-Glucose, 13C5-Glutamine, 13C5-Glutamate, 13C1-Alanine, 13C3-Pyruvate and 13C3-Lactate). The exact volume at each tube was adjusted according to tissue weight (average volume of 200 µl). The samples were homogenized using Precellys 24 tissue homogenizer (Bertin Technologies) precooled to 4°C (3 cycles × 30 s at 6000 rpm, with a 30 s gap between each cycle) and later centrifuged at 18,000 g for 15 min at 4°C. The supernatants were transferred into HPLC glass vials and kept at −80°C prior to LC-MS analysis. |

| Chromatography Summary: | UPLC setup consisted a ZIC-pHILIC column (SeQuant; 150 mm × 2.1 mm, 5 μm; Merck). 5 µl of cells or kidney extracts were injected using an autosampler. Compounds were separated using a 15 minutes gradient, starting at 20% aqueous (20 mM ammonium carbonate adjusted to pH 9.2 with 0.1% of 25% ammonium hydroxide) and 80% organic (acetonitrile), terminated with 20% acetonitrile. Flow rate and column temperature were kept at 0.2 ml/min and 45°C, respectively for a total run time of 27 min |

| MS Comments: | Briefly, Dionex Ultimate ultra-high-performance liquid chromatography (UPLC) system coupled to Orbitrap Q-Exactive mass spectrometer (Thermo Fisher Scientific) was used. The resolution was set to 35,000 at 200 mass/charge ratio (m/z) with electrospray ionization and polarity switching mode to enable both positive and negative ions across a mass range of 67–1000 m/z. |
