产品描述:
CFDA, SE是一种可对活细胞进行荧光标记的细胞染色试剂,不仅用于细胞增殖的体外实验,也可用于追踪细胞在体内的分裂增殖过程。它穿透细胞膜进入细胞后被细胞内的酯酶催化分解成CFSE,CFSE可以偶发性地并不可逆地与细胞内的氨基结合偶联到细胞蛋白质上。在细胞分裂增殖过程中,CFSE 标记荧光可平均分配至两个子代细胞中,因此其荧光强度是亲代细胞的一半,用流式细胞仪或荧光显微镜在490 nm 激发光处可对其进行分析。CFDA, SE标记后的细胞用于体内观察可以长达数周。因此,CFDA, SE常被用来做活细胞检测实验和用荧光电镜观察细胞长期活动的实验。CFDA, SE标记的细胞的激发的发射波长分别为500nm和520nm。
