Fig. 4From: Glycyl-alanyl-histidine protects PC12 cells against hydrogen peroxide toxicityMicrographs representative of shape changes of PC12 cells. PC12 cells were incubated with 5000 μM hydrogen peroxide for 4 h with or without 1 μg/μL of GHH, AHH, AHA, AAH, AGH, GAH, AHG, HAG, HHH, GHA, GGH, or AH carnosine for 4 hBack to article page
