Techniques细胞增殖检测方法大全(下)——荧光染料法
荧光检测一般采用细胞外标记染料(如CFSE、BrdU和EdU)或内源性蛋白(如Ki-67)作为指示物,通过荧光显微镜或流式细胞术进行检测。而流式检测则是将染有不同细胞表面标记的细胞样本经过荧光激发后在流式细胞仪中分析,通过对荧光信号的定量测量来确定不同分子标志物在不同时间点和条件下的表达和变化。两种检测方法都可以用于细胞增殖、表观遗传学和细胞周期等方面的研究
细胞增殖是生物体生长、发育、繁殖和遗传的基础,是生物体的重要生命特征。细胞通常以分裂的方式进行增殖。细胞毒性(cytotoxic)是由细胞或化学物质引起的单纯细胞杀伤事件,不依赖于凋亡或坏死的细胞死亡机理。
根据您实验室现有的实验条件,可选择使用多功能酶标仪的化学发光发检测,也可选择利用荧光显微镜或者流式细胞仪的检测。最常见的细胞增殖和毒性的检测方法有以下几种:
