Fig. 3From: Glycyl-alanyl-histidine protects PC12 cells against hydrogen peroxide toxicityGAH does not directly inhibit LDH enzyme activity. We added 0.1 μg/μL, 1 μg/μL, or 5 μg/μL of GAH to the media of PC12 cells incubated with 5000 μM hydrogen peroxide for 4 h and subsequently measured the LDH activity. All data are shown as mean ± SEBack to article page
