Described is a method for identifying DNA replicating cells, which method comprises the steps of adding during the cultivation of cells a halogenated pyrimidine to the medium, preferably BrUrd, treating the harvested cells by UV irradiation, resuspending the cells in a solution with reduced ionic strength and identifying cells with the incorporated halogenated pyrimidine, e.g. by using labelled antibodies. This method can be combined with the simultaneous detection of cellular markers, e.g. surface antigens, thus, is useful for the diagnosis or prognosis of malignancies as well as the analysis of apoptosis, proliferation and cell-cycle kinetics.
描述了一种鉴定 DNA 复制细胞的方法,该方法包括以下步骤:在细胞培养过程中向培养基(最好是 BrUrd)中加入卤代嘧啶,用紫外线照射处理收获的细胞,在离子强度降低的溶液中重新悬浮细胞,通过使用标记抗体等方法鉴定加入卤代嘧啶的细胞。这种方法可与细胞标记物(如表面抗原)的同步检测相结合,因此可用于恶性肿瘤的诊断或预后,以及细胞凋亡、增殖和细胞周期动力学的分析。
