CFSE 是细胞膜可渗透的,并且很容易在活细胞内积聚,在那里它与细胞内蛋白质共价结合(图 1)。 水解的 CFSE 发出荧光,共价连接的荧光素分子不会从细胞中泄漏。 CFSE 标记的细胞可以在体内监测数周。 因此,CFSE 可用于检测活细胞以及通过荧光显微镜对细胞活动进行长期观察。 CFSE 标记细胞的激发和发射波长分别为 500 nm 和 520 nm。

Staining Procedure1.Prepare 1 mM CFSE solution with DMSO. Dilute it to prepare 10-50 μM CFSE solution with PBS or an appropriate buffer.2.Add CFSE solution with 1/10 of the volume of cell culture medium to the cell culture.3.Incubate the cell at 37ºC for 15 to 30 min.4.Wash cells twice with PBS or an appropriate buffer.5.Observe the cells under a fluorescence microscope with 490 nm excitation and 530 nm emission filters.
