title: Definition of selectable cell surface markers for human chromosomes and chromosome segments in rodent-human hybrids.
abstract: A panel of 22 monoclonal antibodies (MAbs) recognizing 21 distinct human cell surface antigens was tested by mixed hemadsorption assays for reactivity with a large number of rodent-human somatic cell hybrids containing different subsets of the human chromosome complement. The serological typing results permit the assignment of six gene loci determining cell surface antigens to human chromosomes 3, 6, 11, 19, 20, and 22. In addition, analysis of hybrids retaining deleted copies (but no normal homologs) of specific human chromosomes provides regional assignments for 18 gene loci, located on seven different chromosomes. These findings extend and refine the genetic map for human cell surface antigens and identify new selectable markers for defined chromosome segments.
