Description: 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™ 633 exhibits pH-sensitive fluorescence (Ex/Em 634/657 nm at pH ≤5), further enhancing the specificity of staining.
