LysoView™ dyes are fluorescent stains for imaging lysosome localization and morphology in live cells. The dyes accumulate in the low pH environment of the lysosomes, resulting in highly specific lysosomal staining without the need for a wash step. Far-red fluorescent LysoView™ 650 (excitation/emission 650/675 nm) is compatible with super-resolution imaging by SIM and STED.
