The human S11 surface antigens are expressed on fibroblasts and are coded by a gene on the X-chromosome. We have regionally mapped this gene by examining S11 expression on a panel of hybrid lines which had fragmented the X-chromosome either during chromosome-mediated gene transfer, or by interspecies translocation during hybrid cell expansion. using indirect immunofluorescence and the fluorescence-activated cell sorter (FACS), it was possible to isolate antigen-positive and -negative hybrid subpopulations for subsequent genetic analysis. The gene coding S11 could be localized to Xq27-28, between the loci for HPRT and G6PD where genes for the S10 and S12 antigens have been previously mapped. This work demonstrates the value of cell surface antigens and the FACS in somatic cell genetic analysis, and provides evidence for regional clustering of surface antigen loci on the human X-chromosome.
