Sampleprep Summary: | RBC and media samples were extracted at 1:10 and 1:20 dilutions, respectively, in ice-cold 5:3:2 MeOH:MeCN:H2O v/v/v, with vigorous vortexing at 4 degrees C for 30 min. The extraction buffer was supplemented with 40uM 3-13C lactate to allow absolute quantification of lactate isotopologues, including lactate generated via glycolysis ([1,2,3-13C3] enriched) vs. the pentose phosphate pathway ([2,3-13C2] enriched). Supernatants were clarified via centrifugation (10,000 g, 10 min, 4 C) then analyzed by UHPLC-MS. |
