The elimination of malignant B lymphocytes from human bone marrow using monoclonal antibodies DLC-48 and LN-1 and human serum: A preclinical study

Monoclonal antibodies DLC-48 and LN-1 were evaluated for use in purging malignant lymphoma cells from human bone marrow. Using a 51Cr-release assay and sensitive clonogenic assay for the SU-DHL-2 and -4 cell lines, it was established that greater than four logs of malignant lymphoid cells can be eli...

description Monoclonal antibodies DLC-48 and LN-1 were evaluated for use in purging malignant lymphoma cells from human bone marrow. Using a 51Cr-release assay and sensitive clonogenic assay for the SU-DHL-2 and -4 cell lines, it was established that greater than four logs of malignant lymphoid cells can be eliminated from human bone marrow autografts with three treatments of antibody and autologous human serum at a final cell concentration of 1 × 107cells/ml. A combination of DLC-48 and LN-1 was more effective than either antibody alone. Treatment with antibody and autologous serum had no effect on the growth of human hematopoietic progenitor cells. The clinical effects of marrow treatment with DLC-48 and LN-1 will be evaluated in upcoming clinical trials.
