Figure 3.

Change in fluorescence of 7AAMD upon addition of DNA. Dotted lines represent the initial fluorescence intensity of the 7AAMD alone. Subsequent solid lines indicate additions of (A) 6PdC hairpin DNA or (B) 6PdC in a double-strand complex with its complementary strand (6PdC_comp). Note that with double-strand DNA, the 7AAMD fluorescence is quenched upon binding.
