From: Glycyl-alanyl-histidine protects PC12 cells against hydrogen peroxide toxicity
Cell protective effects activity of GAH are concentration-dependent. PC12 cells were incubated with 5000 μM hydrogen peroxide for 4 h without or with different concentrations of GAH (0.00329, 0.0156, 0.0625, 0.25, and 1 μg/μL). All data are shown as mean ± SE of three independent experiments. * indicates significant difference (p < 0.01) between no peptide. LDH = lactate dehydrogenase
