title: A rapid two-dimensional fractionation of DNA restriction fragments.
abstract: Genomic DNA that has been digested with a restriction endonuclease and fractionated by electrophoresis on an agarose gel can be recovered on glass-fiber filters by a new blotting scheme. The DNA fragments in each fraction are then digested with a second restriction nuclease and then separated on a slab gel, resulting in a two-dimensional display of the restriction fragments. This rapid fingerprinting technique is useful in the analysis of complex genomes and in the isolation and cloning of particular sequences.
