Figure 1. Amount of ATP in cell lysates and NAD(P)H production in cells from the line U87 under different culture conditions.
Cells from the line U87 were cultivated for 20 hours at a density of 5000 cells per well in 96-well microplates in DMEM standard culture medium before they received fresh medium with different supplements: FBS: fetal bovine serum, 10%; Glx: GlutaMax, 2 mM; Glu/Gal/Pyr: glucose, galactose, pyruvate: each 25 mM; 0: no Glu/Gal/Pyr. 24 hours later the CellTiter-Glo assay (measuring ATP in cell lysates, left part of the panel) and the CellTiter-Blue assay (measuring NAD(P)H production, right part of the panel) were employed to assess cell viability. Signals obtained from cells cultivated in 25 mM glucose, 10% FBS and 2 mM GlutaMax were set as 100%. Results are presented as mean and standard deviation of 6 wells. Statistical significance was determined by Student's t-test with: *p < 0.05; **p < 0.005; ***p < 0.0005.
