Establishment of a new Epstein-Barr virus-immortalized cell line from chronic lymphocytic leukemia with trisomy of chromosome 12 that produces monoclonal IgM against a sheep RBC antigen
Abstract
Leukemia cells from a patient with chronic lymphocytic leukemia (CLL) were found to bind sheep RBC (SRBC) through their monoclonal surface IgM. A lymphoblastoid cell line was obtained by immortalization of leukemic cells with Epstein-Barr virus (EBV). Cultured leukemic cells were found to have a supernumerary chromosome 12, an abnormality typical of CLL of the B cell type. To our knowledge, this is the first EBV-immortalized cell line from B-CLL cells of known SRBC specificity and the third reported CLL cell line carrying trisomy of chromosome 12.
