应用免疫学的方法制备人白血病细胞异种抗血清,利用该抗血清在发现白血病相关抗原、进行细胞分类、预示复发、治疗效果等方面均有一定的临床价值。本实验系用我室建立的细胞系S—7809和S—7811制备的家兔抗血清,用补体介导细胞毒试验的方法检查各种类型白血病病人的外周血白细胞及骨髓血白细胞,并以正常人的外周血白细胞作对照,结果证明白血病病人的白细胞含有 Immunological methods for the preparation of human leukemia cells heterologous antiserum, the use of the antiserum in the discovery of leukemia-associated antigens, cell classification, predicting relapse, the treatment effect and so on have some clinical value. In our experiment, rabbit antisera prepared by S-7809 cells and S-7811 cells established by our laboratory were used to examine peripheral blood leukocytes and myeloid leucocytes in patients with various types of leukemia by complement-mediated cytotoxicity assay. Normal peripheral blood leukocytes as a control, the results prove leukemia patients contain leukocytes
