A fluorescent anthracene-tagged DNA probe has been shown to respond to various DNA sequences by changes to its emission signal upon duplex formation. The fluorescence response for duplexes containing a single mismatch near the anthracene site has been found to be very sensitive to its composition, with the emission signal increasing for a CA mismatch and decreasing for CT and CC mismatches.
