LysoTracker Green DND-26

LysoTracker Green DND-26 is a fluorescent lysosome-selective staining dye designed for visualization of acidic organelles in fixed and live-cell fluorescence microscopy workflows. The dye accumulates in acidic compartments, enabling bright punctate labeling that supports qualitative tracking of lysosomal distribution and relative changes in lysosome abundance or acidity. Its green emission profile makes it compatible with common fluorescein/GFP filter sets used in cell imaging.

1. Lysosome Fluorescence Microscopy

LysoTracker Green DND-26 is routinely used by cell biologists and imaging specialists to label lysosomes as punctate structures for confocal and widefield fluorescence microscopy. Researchers apply the dye to monitor lysosomal trafficking, changes in lysosomal morphology, and spatial redistribution during cellular perturbations, including endocytic and autophagy-related studies. Because the staining is driven by acidic compartment accumulation, the reagent is commonly selected when lysosome localization is the primary readout rather than a protein-specific marker.

2. Live-Cell Cellular Imaging

LysoTracker Green DND-26 is widely used in live-cell imaging experiments where investigators want a dynamic view of lysosomal compartments over time. In microscopy workflows, the dye is employed to generate time-lapse movies of lysosome movement and to compare relative staining patterns across experimental conditions. Imaging teams often choose this green lysosome dye to integrate with multicolor experiments that already include green-channel reporters, leveraging standard microscope filter sets for practical assay design.

3. Flow Cytometry Lysosome Staining

LysoTracker Green DND-26 supports quantitative flow cytometry workflows that assess lysosome-associated fluorescence on a per-cell basis. In cell analysis pipelines, researchers stain cells with the dye and analyze fluorescence intensity distributions to compare lysosomal staining levels across populations, enabling screening-style comparisons and phenotypic profiling. The reagent's green emission is commonly leveraged with flow cytometers equipped with FITC/488 nm excitation and appropriate emission detection, facilitating straightforward incorporation into existing cytometry panels.

4. Autophagy And Endocytosis Studies

LysoTracker Green DND-26 is frequently selected for mechanistic cell biology studies that examine lysosome involvement in autophagy and endocytic pathways. Researchers use the dye as a lysosomal compartment reporter to visualize how treatments or genetic perturbations influence lysosome abundance, distribution, and apparent acidity-related staining patterns. This application is especially common in laboratories that rely on organelle-level readouts to complement protein marker assays and microscopy-based phenotyping.
