Sample Preparation:

Sampleprep ID:SP002086
Sampleprep Summary:To process cells for assessment of intracellular metabolites, cells were pelleted at 400xg in tubes coated with 0.06% BSA. Supernatant was aspirated and discarded; residual liquid was carefully wicked away from the pellet with a kimwipe. Dry pellets were immediately snap frozen and stored at -80C until processing. To process culture supernatants for assessment of metabolites, supernatant was centrifuged at 400xg to pellet any cells. Cell-free supernatant was then transferred to a fresh tube, snap frozen, and stored at -80C until processing. Ultra-high pressure liquid chromatography-mass spectrometry (UHPLC-MS) was performed by the University of Colorado School of Medicine Metabolomics Core. Metabolites from frozen cell pellets were extracted at 2e6 cells/mL in ice cold 5:3:2 MeOH:acetonitrile:water (v/v/v). Media was thawed on ice and a 10 L aliquot treated with 240 L of the same extraction solution. Extractions were carried out using vigorous vortexing for 30 min at 4C. Supernatants were clarified by centrifugation (10 min, 18,000 g, 4C) and analyzed using a Thermo Vanquish UHPLC coupled to a Thermo Q Exactive mass spectrometer.
