In this paper, the interaction mechanism between mitomycin C and calf thymus DNA has been studied by fluorescence method using EB as an extrinsic fluorescence probe. The results show that mitomycin C can interact with DNA only after being reductively activated by Na2S2O4, and the interaction mode between them should be minor groove binding and partial intercalation. This result further proves that mitomycin C interacts with DNA in the mode of cross-linking.
