Fig. 2From: Inhibition of Astrocyte Glutamate Uptake by Reactive Oxygen Species: Role of Antioxidant Enzymes Hydrogen peroxide-induced inhibition of Glu uptake: protection by DMTU Various concentrations of DMTU were added in the presence of 0.5 mM H2O2 + 25 µM CuSO4 + 100 µM ascorbate. DMTU was added 20 min before incubation with 3H-Glu.Back to article page
