Peripheral blood lymphocytes from donors immunized against Rh antigens were fused with mouse myelomas and heteromyelomas in order to obtain human-mouse hybridomas secreting antibodies specific for these antigens. Three cell lines secreting anti-D IgG and two secreting anti-c IgM were stabilized and produced immunoglobulins for several months. These human monoclonal antibodies were evaluated as reagents for Rh phenotyping. Their complementary activity towards weak D and partial D antigens is examined.
