罗丹明类染料是一种膜渗透性的阳离子荧光探针，可对线粒体膜电位进行特异性识别，从而附着在线粒体中，并产生明亮荧光，在一定浓度下，罗丹明类染料对细胞具有低毒性，因此普遍用于检测动物细胞、植物细胞以及微生物中的线粒体。 Rhodamine dyes are membrane-permeable cationic fluorescent probes that specifically recognize mitochondrial membrane potentials, thereby attaching to mitochondria and producing bright fluorescence, and at certain concentrations, rhodamine dyes have low toxicity to cells, so they are commonly used to detect mitochondria in animal cells, plant cells, and microorganisms
