摘要
Polony DNA sequencing provides an inexpensive, accurate, high-throughput way to resequence genomes of interest by comparison to a reference genome. Mate-paired in vitro shotgun genomic libraries are produced and clonally amplified on microbeads by emulsion PCR. These serve as templates for sequencing by fluorescent nonamer ligation reactions on a microscope slide. Each sequencing run results in millions of 26-bp reads that can be aligned to the reference genome, allowing the identification of differences between sequences.
