title: Selective chemical autoligation on a double-stranded DNA template.
abstract: We show that a double-stranded DNA segment serves as an effective template for spontaneously coupling short pyrimidine oligonucleotides containing terminal -P(O)(O-)S- and BrCH2C(O)NH- groups. The efficiency of this autoligation depends markedly on proper base-pairing between the probe oligomers and the double-stranded target. This chemistry should be useful in designing highly selective probes for double-stranded polynucleotide segments.
