title: New eximer-based tandem systems for SNP detection.
abstract: We report here the design and synthesis of new mono- and bis-pyrene-labeled oligo(2'-O-methylribonucleotide) tandems as perspective probes for SNP detection. The detection strategy is based on the eximer formation when two or more pyrene groups are brought into close proximity upon hybridization of the tandem components with DNA. The potential of SNP detection with tandems of pyrene-labeled oligo(2'-O-methylribonucleotides) by duplex melting curve analysis based on excimer fluorescence registration was demonstrated.
