  • Title: High resolution visual mapping of stretched DNA by fluorescent hybridization.
    Author: Parra I, Windle B.
    Journal: Nat Genet; 1993 Sep; 5(1):17-21. PubMed ID: 8106079.
    Abstract:
    We describe a method for stretching DNA, which, when combined with fluorescent hybridization procedures, forms a new mapping technology that produces a high resolution, vivid, multi-colour image and map. Restriction fragments and cosmid probes were successfully mapped by this procedure with validation by standard restriction mapping. A long range map of a > 200 kilobase region containing five copies of the amplified dihydrofolate reductase gene was easily generated within two days. This DNA mapping procedure offers a significant and rapid alternative to a variety of standard mapping procedures.
