title: [Subregional localization of recombinant cosmids, containing microsatellite sequences, on human chromosome 13].
abstract: Twenty four recombinant cosmids were subregionally localized by fluorescent in situ hybridization on human chromosomes. Fifteen of the clones were found to belong to only one chromosome: 13 clones located on chromosome 13, one located on chromosome 1, and one on chromosome 11. Nine cosmids were located in nuclear organizer regions. The clones gave signals from NOR regions of chromosome 13 and all other chromosomes containing the NOR region. The cosmid probes were selected from the chromosome 13 cosmid library as ones containing microsatellite repeats with motifs GACA, GACT, GATG, TCC, and CA. Each of the 9 clones located in the NOR region contains microsatellites GACA and TCC. Among the 15 clones giving unique signals, we found 9 clones with the GACT microsatellite, and three clones containing one of the microsatellites GATG, TCC, and CA. These microsatellite-containing clones can be used to make polymorphic genetic markers for fine genetic mapping of chromosome 13.
