试验表明，经铜离子与维生素Ｃ协同作用后，噬菌体核酸的修复率随作用时间延长与维生素Ｃ浓度增加而降低；ｆ＿２噬菌体核酸修复率低于Ｔ＿２噬菌体者。从Ｔ＿２噬菌体提取的ＤＮＡ经上述药物作用后，电泳带明显增长。
The results showed that the repair rate of phage nucleic acid decreased with the prolongation of action time and the increase of vitamin C concentration through the synergistic effect of copper ion and vitamin C. The nucleic acid repair rate of phage f_2 was lower than that of T_2 phage. DNA extracted from T 2 bacteriophage by the above drugs, the electrophoresis band increased significantly.
