title: Alloxazine as a ligand for selective binding to adenine opposite AP sites in DNA duplexes and analysis of single-nucleotide polymorphisms.
abstract: Alloxazine can bind to adenine selectively over other nucleobases opposite an abasic site in DNA duplexes (5'-TCC AGX GCA AC-3'/3'-AGG TCN CGT TG-5', X=AP site, N=A, T, C, G) with a dissociation constant of 0.82 microM (pH 7.0, I=0.11 M, at 5 degrees C), and it is applicable to SNPs typing of PCR amplification products based on the binding-induced fluorescence response.
