Metabolic pathways that generate various lactate isotopomers and isotopologues in cells, traced with [1,2-13C2]glucose. 4T1 cells were incubated in serum-free RPMI 1640 medium containing 6 mM [1,2-13C2]glucose for 12 hours in a humidified CO2 incubator and culture supernatant was collected for LC-MS analysis as described in Materials and Methods. The figure explain the generation of various lactate isotopologues from [1,2-13C2]glucose.
