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.
