    • A leukemia lymphoma reactive monoclonal antibody which, relative to normal peripheral blood cells, strongly reacts with one or more leukemia lymphoma cell specimens selected from the group consisting of B non-Hodgkin's lymphoma cells, B chronic lymphocytic leukemia cells, B prolymphocytic leukemia cells, B hairy cell leukemia cells, and B acute lymphoblastic leukemia cells. More specifically, a novel hybrid cell line, designated 2B-4G9, for production of monoclonal antibody specific for a unique cell surface epitope associated with a wide variety of human lymphomas and leukemias is provided. This invention also provides a method for producing the new monoclonal antibody and to diagnostic procedures using the new monoclonal antibody to detect various leukemias and lymphomas. Also disclosed are methods of using the antibody or reactive fragments of the antibody for the treatment of leukemia-lymphoma patients.
    • 相对于正常外周血细胞的白血病淋巴瘤反应性单克隆抗体与一种或多种选自B非霍奇金淋巴瘤细胞,B型慢性淋巴细胞性白血病细胞,B型淋巴细胞性白血病细胞,B型淋巴细胞性白血病细胞,B型淋巴细胞白血病细胞, 毛细胞白血病细胞和B急性淋巴细胞白血病细胞。 更具体地,提供了一种新颖的杂交细胞系,其命名为2B-4G9,用于产生与多种人类淋巴瘤和白血病相关的特异性细胞表位表位特异的单克隆抗体。 本发明还提供了用于产生新的单克隆抗体的方法和使用新的单克隆抗体检测各种白血病和淋巴瘤的诊断程序。 还公开了使用抗体或抗体的反应性片段用于治疗白血病淋巴瘤患者的方法。
