title: Chromosome assignment of monoclonal antibody-defined determinants on human leukemic cells.
abstract: Hybrids formed between human acute lymphoblastic leukemia (ALL) cells and mouse myeloma have been used to determine the chromosomal location of genes required for the expression of several monoclonal antibody (mAb)-defined cell surface antigens on ALL cells. Cloned hybrids were tested for antibody binding, immunoprecipitation of the relevant protein, chromosome isoenzyme markers and karyotype. Two antigens of those studies could be definitively mapped, OKT10/p45 to chromosome 4 and BA-2/p24 to chromosome 12. mAb BA-2 reacts with the same protein as another mAb designated 609-29 (anti-teratocarcinoma). Reactivity with the latter mAb has been previously shown to segregate with chromosome 12.
