以抗人转铁蛋白受体单克隆搞体OKT9．为抗体．运用酶联免疫组ABC染色法．对儿童急件白血病不同病期的骨髓进行ABC染色。结果发现白血病未治期及部分缓解期转铁蛋白受体（TfR）表面达显著高于健康对照组（P＜0．01，P＜0．025）。而完全缓解期TfR表达与健康对照组比较无明显差别（P＞0．5）。提不TfR表达与白血病细胞增殖有关，对白血病的早期诊断及治疗有重要意义。
Anti-human transferrin receptor monoclonal OKT9. For the antibody. ABC staining method using enzyme-linked immunosorbent assay. Bone marrow from different stages of childhood acute leukemia ABC staining. The results showed that the surface expression of transferrin receptor (TfR) in leukemia and partly in remission stage was significantly higher than that in healthy controls (P <0.01, P <0.025). However, TfR expression in complete remission was not significantly different from that in healthy controls (P> 0.5). TfR expression and leukemia cell proliferation related to the early diagnosis and treatment of leukemia is of great significance.
