Description DASPEI is a cationic styrenyl mitochondrial dye characterized by a large Stokes shift and excitation/emission wavelengths at 550/573 nm, yielding robust chromogenic properties. It effectively stains mitochondria in live cells and labels presynaptic nerve endings regardless of neuronal activity [1].
In vitro 使用方法:1. 制备DASPEI储存液。以DMSO配制10 mM DASPEI,分装后于-20°C或-80°C避光冷藏。1.2 将储存液用预热的无血清细胞培养基或PBS稀释至5-10 μM制得工作液。根据实验需要调节浓度,临用现配。2. 细胞染色(悬浮细胞):2.1 离心后洗涤细胞两次,细胞浓度调至1×10^6/mL。2.2 加入1 mL DASPEI工作液,常温孵育30-60分钟。2.3 400 g离心3-4分钟后去除上清,用PBS洗涤两次。2.5 重悬细胞后,应用荧光显微镜或流式细胞仪进行分析。3. 细胞染色(贴壁细胞):3.1 细胞播种于无菌盖玻片上。3.2 移除盖玻片上多余的培养基。3.3 加入100 μL染色工作液覆盖细胞,轻轻晃动盖玻片,孵育30-60分钟。3.4 移走染色液,用培养基清洗2-3次,随后进行荧光显微镜观察。
