[3] suggested four interactions between DNA and Hoechst 33258, could be mediated by DNA sequence, charge on dye, dye interactions and structure of the dye. Sequence-mediated binding provides specificity in that Hoechst dyes bind in the minor groove requiring a specific sequence (often four A-T base pairs).
