Sampleprep Summary: | Pellet was resuspended in extraction buffer (80% Methanol, 25 mM Ammonium Acetate and 2.5 mM Na-Ascorbate prepared in LC-MS water, supplemented with isotopically-labelled amino acid standards [Cambridge Isotope Laboratories, MSK-A2-1.2], aminopterin, and reduced glutathione standard [Cambridge Isotope Laboratories, CNLM-6245-10]). Samples were vortexed for 10 sec, then centrifuged for 10 minutes at 18,000 g to pellet cell debris. The supernatant was divided into two tubes and dried on ice using a liquid nitrogen dryer. One tube of dried sample was used for polar metabolite detection. Dried samples were resuspended in 25 μL water |
