Collection:

Collection ID:CO002541
Collection Summary:PTCs were isolated as previously described(PMID: 32484794). Briefly, kidneys were excised in ice-cold HBSS buffer. The kidneys were sliced and chopped into pieces (~0.5–1 mm) on ice using a surgical scalpel. The chopped kidneys were transferred into an HBSS solution containing 1 μg/μL collagenase/dispase (Sigma Aldrich, Cat. # 10269638001) and incubated for 25 minutes at 370 C. The cells were filtered through a 40-μm nylon cell strainer (Corning, Cat. # 431750) and washed twice with cold HBSS. For PTC isolation, the cells were stained with PE-conjugated antiCD133/prominin-1 antibody (Invitrogen, Cat. # 12-1331-82) according to the manufacturer's instructions. PE+ cells were isolated by Aria III flow cytometry-based cell sorting.
Sample Type:Proximal tubular cells

Treatment:

Treatment ID:TR002560
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:

Chromatography ID:CH002961
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:

MS ID:MS003757
Analysis ID:AN004010
Instrument Name:Thermo Q Exactive Orbitrap
Instrument Type:Orbitrap
MS Type:ESI
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.
