title: Isolation and characterization of cell hybrids containing human Xp-chromosome fragments.
abstract: We have subjected C12D, a Chinese hamster hybrid containing only the human X chromosome, to 6-thioguanine selection. The majority of the derivative clones retained rearranged Xp-fragments, which were characterized by using a combination of enzyme markers, DNA probes, and in situ hybridization. Two of these, TG2 and TG5sc9.1, contained only an Xpter----p21 fragment and should be an ideal resource for directed cloning from this region. A possible mechanism for the specific retention of Xp-fragments is discussed.
