Protection against hydroxyl radical-induced calf thymus DNA damage by oxidized and reduced form of MT-I and MT-II proteins from sweet potato tuberous roots. Lanes 1-3 were 2.5, 5, and 10 mg/mL MT-I and MT-II additions. Only calf thymus DNA was used for blank test (B), and the control test was without MT-I and MT-II additions (C).
