Collection:
| Collection ID: | CO002444 |
| Collection Summary: | Cells were spun down and washed once with pre-warmed PBS and metabolites were immediately extracted or stored at -80℃ until extraction. |
| Sample Type: | Cultured cells |
Treatment:
| Treatment ID: | TR002463 |
| Treatment Summary: | CD8+ T cells were isolated from spleens and lymph nodes from C57BL/6J mice. Cells were left naïve or activated with plate-bound anti-CD3 and soluble anti-CD28 for 24 hours. CD8+ T cells were counted and resuspended in full media containing 11 mM [U-13C]glucose at 2 E6 mL-1. Normal FBS was substituted with dialyzed FBS. Cells were collected for LC-MS analysis 4-6 hrs post incubation. |
Sample Preparation:
| Sampleprep ID: | SP002457 |
| Sampleprep Summary: | Cells were spun down and washed once with pre-warmed PBS and metabolites were immediately extracted by adding methanol:water (80:20, v/v) extraction solution, sonicated and stored at -80 °C for at least 2 hrs to precipitate the proteins. Supernatant after centrifugation at 14,000xg for 10 minutes was dried under nitrogen gas. Metabolites were then reconstituted using ACN:water (50:50, v/v) overnight at 4 °C. Soluble metabolites after centrifugation at 14,000xg for 10 minutes were subjected to analysis by liquid chromatography mass spectrometry (LC-MS). |

| MS Comments: | The optimized ESI Q-TOF parameters for MS experiments were: ion polarity, negative; gas temperature, 325 °C; drying gas, 10 L min-1; nebulizer pressure, 45 psig; capillary voltage, 4,000 V; fragmentor, 140 V; skimmer, 65 V; mass range, 50-1100 m/z; acquisition rate, 1.5 spectra s-1; instrument state, extended dynamic range (1700 m/z, 2 GHz). Spectra were internally mass calibrated in real time by continuous infusion of a reference mass solution using an isocratic pump connected to a dual sprayer feeding into an electrospray ionization source. Data were acquired with MassHunter Acquisition software. A metabolite database with retention times based on the ion-pairing method was developed using Agilent MassHunter PCDL manager software. The isotopologue peak extractions were achieved by Agilent MassHunter Profinder software. |
