title: Microdissection and microcloning of the long arm of human chromosome 7.
abstract: DNA-fragments from the region of the long arm of human chromosome 7 to which the CF-locus has been mapped recently were isolated by microdissection and microcloning. We developed a new fixation procedure resulting in inserts of 1.0-7.0 kb in length with a mean value of 2.9 kb. Regional mapping of three clones on 7q was carried out by the use of different hybrid cell lines containing fragments of human chromosome 7.
