细胞工程及基因工程技术的发展使得对疾病的研究进入分子水平。白细胞表面分化抗原的单克隆抗体已逐步用于白血病、淋巴瘤的细胞分型,开始成为一种常规方法。同时也已开始在基因水平进行这 The development of cell engineering and genetic engineering technology has brought the research on diseases into the molecular level. Monoclonal antibodies against leukocyte surface differentiation antigens have been gradually used in cell types of leukemias and lymphomas and have become a routine method. It has also begun to do this at the genetic level
