产品介绍
​ CFDA SE细胞增殖与示踪检测试剂盒是基于CFDA SE对细胞进行增殖及示踪检测的试剂盒,本试剂盒由CFDA SE粉末、溶剂及染色缓冲液组成。 CFDA SE是二乙酸荧光素(Fluorescein diacetate,FDA)的衍生物,具有细胞膜渗透性,本身不具有荧光发光性。当CFDA SE穿透细胞膜进入活细胞后,可被胞浆内的酯酶催化生成羧基荧光素琥珀酰亚胺酯(carboxyfluorescein succinimidyl ester,CFSE),可发强烈的绿色荧光,不能穿透细胞膜,能完好的保留在胞内。CFSE还可自发并不可逆地与细胞内的氨基共价结合从而偶联到细胞蛋白质上。同时,过量且未被偶联的CFDA SE通过被动扩散回到细胞外培养基内,被后续清洗步骤所清除。经CFDA SE标记的非分裂细胞的荧光非常稳定,稳定标记的时间可达数月,因此非常适用于细胞群落分析。 CFDA SE标记细胞的荧光非常均一,优于以前使用的其他细胞示踪荧光探针如PKH26,并且分裂后的子代细胞的荧光分配也很均一。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,荧光强度变为亲代细胞的一半,通过流式细胞仪(FL1通道)根据荧光强度的不同,可检测出未分裂细胞,分裂一次(1/2的荧光强度),二次(1/4的荧光强度),三次(1/8的荧光强度),以及更多分裂次数的细胞。CFDA SE可检测分裂次数多达八次甚至更多。经CFDA SE标记的细胞可用于体外和体内增殖研究,且具有不会使邻近细胞染色的功能。CFDA SE最常用于淋巴细胞的增殖检测,也可用于成纤维细胞,NK细胞等其他细胞的增殖检测。 CFDA SE标记细胞呈绿色荧光,除了流式细胞仪检测细胞增殖外,还可用荧光显微镜进行均一染色的细胞示踪观察。 组分: 组分
