Establishment of a human/Chinese hamster hybrid clone panel

Combined with the chromosome G-banding, followed by Giemsa-11 techniques and chromosomal marker isozyme analysis, 6 out of 200 subclones have been analyzed in detail. A primary hybrid clone panel has been established, which can be used to map genes on chromosomes 4, 5, 8, 12, 20 and 22. Since the panel contains deleted chromosomes 4, 5, 8 and 12, genes on these chromosomes can be mapped regionally.
