ABSTRACT
<p><b>OBJECTIVE</b>To analyze the reactive pattern and its clinical significance of ZCH-7-2D3 monoclonal antibody on leukemia cells.</p><p><b>METHODS</b>Bone marrow samples from 100 leukemia patients (male 59 female 41, 34 cases of children and 66 adults, aged 11 months - 77 year) were collected. A CD45 gating strategy and multi-parameter flow cytometry were used to analyze the leukemia cells.</p><p><b>RESULT</b>The positive rate (10/31) of 2D3 antibody on acute lymphocytic leukemia (ALL) patients was significantly lower than that (39/55) of acute myelogeneous leukemia (AML) (P <0.01). 2D3 was positive for all three cases of B/myeloid mixed lineage leukemia, but negative in 6 cases of chronic myelogeneous leukemia (CML), significantly lower than that in AML (39/55, P<0.01) patients. There was no difference between the positive rates of chronic lymphocytic leukemia (CLL, 3/5) and B lineage ALL (9/28, P = 0.2389). The antibody was not found to recognize the differentiation stages of either ALL and AML subtypes.</p><p><b>CONCLUSION</b>2D3 monoclonal antibody primarily recognizes AML cases. Further studies on cloning of gene encoding the antigen protein and its biological functions are warranted.</p>
