Fig. 8From: Glycyl-alanyl-histidine protects PC12 cells against hydrogen peroxide toxicityGAH protects PC12 cells as measured by the CCK-8 assay. PC12 cells were exposed to 100 μM hydrogen peroxide. Cell viability was measured using the CCK-8 assay at the start and after 24 h incubation. All data are shown as mean ± SE of three independent experiments (p < 0.01)Back to article page
