title: Separation of oligonucleotides with single-base mutation by capillary electrophoresis using specific interaction of metal ion with nucleotide.
abstract: A unique tactic for the separation of single-base sequential isomers of oligomeric single-stranded DNA by a CE separation system employing the specific interaction of metal ion with nucleotide was demonstrated, enabling the separation of the mixture of a 12-mer oligonucleotide and its single-base mutants, as well as their positional isomers.
