title: Constructing contigs from large-insert clones.
abstract: This unit describes three approaches that are widely used to define alignments between overlapping clones bearing large-insert genomic DNA and to generate extensive contiguous overlapping sets of clones (contigs). The three approaches are sequence-tagged site (STS) content mapping, repetitive-element hybridization fingerprinting, and Alu-PCR fingerprinting. Methods for isolating the necessary BAC DNA suitable for automated fluorescent sequencing and generating new STS markers are discussed in support protocols. An alternate protocol presents repetitive-element hybridization fingerprinting to detect overlaps and build contigs with full-genomic YAC libraries.
