JC-1 (CBIC2) 是一种广泛用于检测线粒体膜电位的理想荧光探针。JC-1 染料以电势依赖性的方式积聚在线粒体内,可以用来检测细胞、组织或纯化的线粒体膜电位。正常线粒体内,JC-1 聚集在线粒体基质中形成聚合物,聚合物发出强烈的红色荧光 (Ex=585 nm, Em=590 nm) ;在线粒体膜电位较低时,JC-1不能聚集在线粒体的基质中,产生绿色荧光 (Ex=514 nm, Em=529 nm) 。
生物活性 | JC-1 (CBIC2) is an ideal fluorescent probe widely used to detect mitochondrial membrane potential. JC-1 accumulates in mitochondria in a potential dependent manner and can be used to detect the membrane potential of cells, tissues or purified mitochondria. In normal mitochondria, JC-1 aggregates in the mitochondrial matrix to form a polymer, which emits strong red fluorescence (Ex=585nm, Em=590nm); When the mitochondrial membrane potential is low, JC-1 cannot aggregate in the matrix of mitochondria and produce green fluorescence (ex=514nm, em=529nm)[1]. |
体外研究 (In Vitro) | JC-1 染色液的配制 1.1 制备储存液 用 DMSO 配制 5 mg/mL 的 JC-1。如用 1 mL DMSO 溶解 5 mg JC-1。 注:1) JC-1 储存液建议分装后于 -20℃ 或 -80℃ 避光保存。 1.2 工作液的配制 用预热好的无血清细胞培养基或 PBS 稀释储存液,配制成 1-20 μg/mL 的 JC-1 工作液。 注:1) 请根据实际情况调整 JC-1 工作液浓度,且现用现配。 2) 如果 JC-1 进入细胞的效果不好,可向工作也液中加入适量 20% Pluronic F127 溶液,终浓度为 0.02-0.05%,Pluronic F127 可以防止 JC-1 在缓冲液中聚合并帮助其进入细胞。 JC-1染色 1) 以6孔板为例进行细胞铺板,密度为 5×105cells/mL。37℃,5% CO2培养箱培养过夜。 注:进行凋亡诱导时的细胞密度建议不超过 1×106/mL,也可根据自己的细胞类型培养至合适的密度。 2) 取 0.5 mL 细胞悬液至无菌的离心管内。 3) 400 g 离心 3-5 min;弃上清。 4) 用 1 mL JC-1 工作液重悬细胞,于 37℃,5% CO2培养箱孵育 15-30 min。 5) 室温条件 400 g 离心 5 min;吸掉上清。 6) 用 2 mL 细胞培养液或者缓冲液重悬细胞,之后室温条件 400 g 离心 5 min;弃上清,重复两次。 7) 用 1 mL 新鲜培养液或者缓冲液重悬细胞,立刻进行后续的流式分析或荧光显微镜观察。 8) 数据分析 (流式细胞仪) :含有红色 JC-1 聚集物的健康细胞线粒体用 FL2 通道检测;含有绿色 JC-1 单体的凋亡或不健康细胞用 FL1 (FITC) 通道检测。 注:若用于酶标仪检测,用 300 μL 缓冲液重悬细胞;然后按照每孔 100 μL 的量将染色好的细胞转移到不透光的 96 孔板内,即可进行荧光酶标板分析。
