title: Efficiency of various strategies and materials to generate new markers: saturating the region 5q11.2-q13.3 with 30 new randomly distributed clones.
abstract: Several different strategies and materials were used for saturating the region 5q11.2-q13.3 with new, randomly distributed markers: isolation of human clones from three chromosome-5-specific libraries (a BssHII endclone phage library from the somatic cell hybrid H64 and two total genomic phage libraries from radiation hybrids IH12 and IH132), as well as Alu-PCR from chromosome-5-specific radiation hybrids with overlapping fragments in the region around the spinal muscular atrophy locus, followed either by direct isolation of Alu-PCR products or hybridization of Alu-PCR products to chromosome-5-gridded cosmid libraries. 253 human phage and cosmid clones were mapped to various parts of chromosome 5 by deletion mapping to somatic cell hybrid panels. 30 of these clones were mapped into the region 5q11.2-q13.3, 9 of which are flanking rate cutting BssHII-sites, known to be, often, starting points for genes. They represent excellent starting material for the development of new polymorphic markers and sequence-tagged sites, for YAC screening and building of contigs, as well as for direct isolation of genes.
