title: Screening of a mouse/human Y-chromosomal cosmid library for gene candidates and markers by using (short) oligonucleotide probes.
abstract: A comprehensive approach is described for the identification of sequences of interest from a human Y chromosomal cosmid library via (short) consensus oligonucleotide probes. It involves the ordering of cosmid clones grown in microtiter plates onto small filter membranes by a robot workstation. A high number of the clones are characterized by their repetitive sequence content, either by ubiquitously interspersed simple tandem blocks or by Y-specific elements. The Y chromosomal repeat (DYZ2) appears underrepresented in the library. In contrast many novel microsatellite marker systems can now be developed for the Y chromosome on the basis of the simple repeat blocks described here. Though novel genes were not yet delineated so far, a number of candidate sequences with high coding potential and other interesting characteristics are described.
