LysoTracker Red（Cat No.:I044993）is a fluorescent dye specifically designed for labeling and tracking acidic organelles, particularly lysosomes, in live cells. It is a weakly basic amine conjugated to a red-emitting fluorophore, allowing it to selectively accumulate in low-pH environments. With excitation/emission maxima around 577/590 nm, it provides bright, photostable staining suitable for fluorescence microscopy and live-cell imaging. LysoTracker Red is commonly used to study lysosomal dynamics, autophagy, and intracellular trafficking. Its high specificity and low cytotoxicity make it ideal for real-time visualization of lysosomal compartments in cellular and molecular biology research.
