Collection:
Collection ID: | CO002840 |
Collection Summary: | CD8+ T cells and NK cells were purified by negative selection from freshly prepared mouse splenocytes (wild type vs ACSS2 knockout C57Bl/6 mice). |
Sample Type: | Splenocytes |
Treatment:
Treatment ID: | TR002856 |
Treatment Summary: | Cells were incubated up to 3 hours in the in 100 or 500 µM 13C2-acetate and treated with vehicle (DMSO) or an ACSS2 inhibitor (VY-3-135). |
Sample Preparation:
Sampleprep ID: | SP002853 |
Sampleprep Summary: | Cells were pelleted and washed with ice-cold PBS before extraction of metabolites in 80% methanol. Samples were centrifuged at 4 °C two times (18,000 x g). Deproteinated supernatants were stored at -80 °C prior to analysis. |

Chromatography:
Chromatography ID: | CH003338 |
Chromatography Summary: | Hydrophilic interaction liquid chromatography (HILIC) was performed at 0.2 ml/min on a ZIC-pHILIC column (150 x 2.1 mm, 5 µM particle size, EMD Millipore) with a ZIC-pHILIC guard column (20 x 2.1 mm, EMD Millipore) at 30 °C. Solvent A was 20 mM ammonium carbonate, 0.1% ammonium hydroxide, pH 9.2, 5 µM medronic acid, and solvent B was acetonitrile. The gradient was 85% B for 2 min, 85% B to 20% B over 15 min, 20% B to 85% B over 0.1 min, and 85% B for 8.9 min. The autosampler was held at 4 °C. For each analysis, 5 µl of sample was injected. |

MS Comments: | The following parameters were used for the MS analysis: sheath gas flow rate, 30; auxiliary gas flow rate, 5; sweep gas flow rate, 0; auxiliary gas heater temperature, 200 °C; spray voltage, 3.6 kV for positive and negative modes; capillary temperature, 325 °C; and funnel RF level, 65. Samples were analyzed by full MS with polarity switching. Full MS scans were acquired at 60,000 resolution with 2 microscans and a scan range of 72-1080 m/z, automatic gain control (AGC) target of 5e6, and maximum injection time (IT) of 200 ms. |
