业已表明姊妹染色单体交换(SCE)是一种十分敏感的染色体损伤的指标。Hoechst 加Giemsa 染色技术不仅简化了检测SCE 的方法,也为研究细胞群体分裂动力学提供了一种新工具。
Sister chromatid exchange (SCE) has been shown to be a very sensitive indicator of chromosomal damage. Hoechst plus Giemsa staining not only simplifies the method of detecting SCE, but also provides a new tool for studying cell population cleavage kinetics.
