MitoSOX Red 是一种具有特异性和细胞膜渗透性且靶向活细胞线粒体的新型荧光探针。MitoSOX Red 进入线粒体后会被超氧化物氧化,而不会被其他 ROS 或 RNS 生成系统氧化。MitoSOX Red 随后与线粒体内核酸结合,产生强红色荧光。MitoSOX Red 可以作为荧光指示剂,特异性检测超氧化物。超氧化物歧化酶 (Superoxide dismutase,SOD) 能够预防 MitoSOX Red 氧化。
HKSOX-1m (5 6-mixture) serves as a mitochondria-targeting O2 fluorescent probe with an excitation emission wavelength of 509 534nm (green), showcasing exceptional selectivity and sensitivity for O2 across a wide pH spectrum and in the presence of strong oxidants and prevalent reductants within cells.
MitoPerOx is a ratiometric fluorescent probe that can be used to assess changes in lipid peroxidation within mitochondria. It is composed of a BODIPY fluorophore conjugated via a dienyl link to a triphenylphosphonium cation component that drives its accumulation in mitochondria. MitoPerOx displays an excitation maximum of 495 nm and exhibits a shift in emission maxima from 590 to 520 nm upon mitochondrial lipid peroxidation, enabling determination of ratiometric measurements of lipid peroxidation in live cells.
