抗原异质性是正常的和人类上皮赘生物的基本特性。这对于理解恶性肿瘤细胞的基木的生物学特性及对抗体在核放射成像,肿瘤诊断及免疫治疗的应用中有广泛的意义.加之,在免疫化学同质条件下,不同个体细胞及亚群中的单克隆抗体的数量经常存在明显的差异.在应用纯单克隆抗体OC—125作为抗原示踪剂对卵巢赘生物进行免疫组织学的研究中,我们观 Antigen heterogeneity is a fundamental characteristic of normal and human epithelial neoplasms. This is of great significance for understanding the biological characteristics of basal cells of malignant tumor cells and the application of antibodies to nuclear radioimaging, tumor diagnosis and immunotherapy. In addition, in immunochemically homogeneous conditions, different individual cells and subpopulations There is often a significant difference in the number of monoclonal antibodies in the application of monoclonal antibody OC-125 as an antigen tracer on ovarian neoplasms immunohistochemistry research, we
