摘要
Immuntoxins were synthesized by conjugating a plant toxic ricin with to three different monclonal antibodiesMoAb) directed against markers of human pre- B lymphocyte leukemic cells. It is useful to eliminate residual leukemic cells from bone marrow for preventing leukemia relapse after autologous bone marrow transplantation(ABMT). In the present work, the elimination of human leukemic cell line (Nalm-6) by three immunotoxins (anti-CD9 and anti-CD10) were observed. In addition, the proliferation of hematopoietic progenitors (CFU-GM. BFU E and CFU- mix) were not apparently inhibited by the immunotoxins in the range of effective concentrations. The possibility for utilizating immunotoxins in ABMT was discussed.
