COA 产品使用指南

CFDA-SE 是一种可穿透细胞膜的荧光染料,其能与胞内细胞骨架蛋白中的游离胺基反应,最终形成具有荧光的蛋白复合物。该染料进入细胞后主要定位于细胞膜、细胞质和细胞核,在细胞核的染色效果最强。CFDA-SE 染料可用于检测细胞增殖,CFDA-SE 可随着细胞的分裂增殖而被子代细胞均匀继承,其含量的衰减与细胞分裂次数成正比,该荧光信号可在 488 nm 的激发光下进行检测,并可通过流式细胞仪进行分析。

    生物活性

    CFDA-SE is a fluorescent dye that can penetrate the cell membrane. It can react with the free amine group in the cytoskeleton protein inside the cell, and finally form a protein complex with fluorescence. After entering the cell, CFDA-SE locates in the cell membrane, cytoplasm and nucleus, and the fluorescence staining is strongest in the nucleus[1]. CFDA-SE dye can be uniformly inherited by the cells with cell division and proliferation, and its attenuation is proportional to the number of cell divisions. This phenomenon can be detected and analyzed by flow cytometry under the excitation light of 488 nm, and can be used to detect the proliferation of cells[1].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
