Protective effects of RCP2, RCP3, and RCP5 from collagen hydrolysate of redlip croaker (P. polyactis) scales on plasmid DNA damaged by H₂O₂ at the concentration of 3.0 mg/mL. (A) native pBR322DNA; (B) pBR322DNA treated with FeSO₄ and H₂O₂; (C) pBR322DNA treated with FeSO₄, H₂O₂ and GSH (1.0 mg/mL); (D) pBR322DNA treated with FeSO₄, H₂O₂ and RCP2; (E) pBR322DNA treated with FeSO₄, H₂O₂ and RCP3; (F) pBR322DNA treated with FeSO₄, H₂O₂, and RCP5. The image is chosen from one of three experiments.
