Figure 7. Consumption of dissolved molecular oxygen by Q-SG. BrQ and GSH were previously incubated for 30 min to guarantee the total conversion to Q-SG. The reaction conditions were BrQ (10 µM) and GSH (100 µM) in PBS, pH 7.4, at 37°C. Ascorbic acid (500 µM; VC) was added at the indicated time. Q-SG = nucleophilic substitution product; BrQ = bromoquinone; GSH = glutathione.
