[Monoclonal antibodies to RPMI-1788 lymphoblastoid line cells]
Monoclonal antibodies IPO-1--IPO-8 against surface antigens of B-lymphoblastoid cell line RPMI-1788 were prepared. Murine hybridomas were obtained by fusion of immune spleen cells and myeloma cells. Screening of specific antibody production was carried out by indirect immunofluorescence. Expression of these antibodies against a panel of 11 human cell lines was carried out by indirect immunofluorescence. Expression of antigens detected with IPO-1--IPO-8 were investigated on peripheral blood cells of healthy individuals and patients with CLL, ALL, myeloma and on lymph node cells of patients with Hodgkin's disease. Specificity of these MoAbs is discussed. IPO-5 is shown to react with the HLA-related determinant. The antibody IPO-3 appears to recognize a differentiation antigen of human B cells.
