Study ID	ST002365
Study Title	[U-13C]glutamine tracing in activated WT, GOT1 or GLUD1 knockout CD8+ T cells
Study Summary	WT, GOT1 knockout or GLUD1 knockout CD8+ T cells were activated with plate-bound anti-CD3 and soluble anti-CD28 for 24 hours. CD8+ T cells were pulsed with [U-13C]glutamine for 4-6 hours. Intracellular glutamine-derived glutamate and α-ketoglutarate levels were quantified using MS.

Sample Preparation:

Sampleprep ID:	SP002460
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).
