Figure 5. Exposure to redox cycling quinones induces H2O2 production.

Figure 5

BEAS cells were exposed to DMSO (vehicle) or the indicated concentrations of 1,2-NQ, 1,4-NQ, 9,10-PQ, BQ, or H2O2 for 18 min. H2O2 was measured in apical media as fluorescence at excitation λ= 545 nm, emission λ= 590 nm following a 30 min incubation in the presence of HRP and Amplex Red. n = 3, mean +/− SEM.
