title: Dideoxy DNA sequencing with end-labeled oligonucleotide primers.
abstract: End-labeled oligonucleotide primers may be used effectively as the source of radiolabel in DNA sequencing by the dideoxy method. The approach is demonstrated with various end-labeled oligonucleotides, including a commercially prepared universal primer and a mixed-sequence probe. Single-stranded (M13) or denatured double-stranded template may be used. The end-labeled primers and their extension products may be stored for weeks. The method is useful for identification of clones isolated by oligonucleotide hybridization and it provides a convenient, economical alternative to the use of alpha-labeled deoxynucleoside triphosphate.
