title: Reliable and efficient direct sequencing of PCR-amplified double-stranded genomic DNA template.
abstract: Modified PCR amplification and direct sequencing procedures for the double-stranded genomic DNA template are described. Advantages of the approach we describe are: background artifact bands previously observed using high-molecular-weight DNA as a template were eliminated by this protocol; no gel purification or subcloning of the PCR-amplified double-stranded fragment was required prior to direct sequencing; and sequences of 300 nucleotides can be easily read even after a single loading. The successful use of the modified dideoxynucleotide chain-termination method for direct sequencing of both strands demonstrates the efficiency of this technique for removing sequencing artifacts and for producing reliable sequence data.
