Study IDST002363
Study Title[U-13C]glucose tracing in NT, AOA or EGCG treated activated CD8+ T cells
Study SummaryCD8+ T cells were activated with plate-bound anti-CD3 and soluble anti-CD28 for 24 hours without (NT), or with AOA (250uM) or EGCG (500uM) treatment. CD8+ T cells were pulsed with [U-13C]glucose. Intracellular glucose-derived glutamate levels were quantified using MS.

Project Type:MS quantifying intracellular glutamate levels
Project Summary:CD8+ T cells were activated with plate-bound anti-CD3 and soluble anti-CD28 for 24 hours without (NT), or with AOA (250uM), or EGCG (500uM) treatment. CD8+ T cells were pulsed with [U-13C]glucose for 4-6 hours. Intracellular glucose-derived glutamate levels were quantified using MS.

Collection:

Collection ID:CO002445
Collection Summary:Cells were spun down and washed once with pre-warmed PBS and metabolites were immediately extracted or stored at -80℃ until further extraction.
Sample Type:Cultured cells

Treatment:

Treatment ID:TR002464
Treatment Summary:CD8+ T cells were isolated from spleens and lymph nodes from C57BL/6J mice. Cells were activated with plate-bound anti-CD3 and soluble anti-CD28 for 24 hours, without (NT) or with AOA (250uM) or EGCG (500uM) treatment. 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:SP002458
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).

Analysis ID:AN003858
Instrument Name:Agilent 6520 QTOF
Instrument Type:QTOF
MS Type:ESI
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.
