| Targets |
Green DND-26 targets lysosomes, the acidic organelles responsible for cellular degradation and recycling. The probe does not have a traditional pharmacological target but rather functions as a fluorescent marker for lysosomes. The weak base moiety of the dye is protonated in the acidic environment of lysosomes (pH ~4.5-5.0), causing the dye to become trapped within the organelle. The fluorescein group provides green fluorescence that allows for visualization and quantification of lysosomal content and dynamics in living cells.

| ln Vitro |
1. Working solution configuration: 1.1 Centrifuge the solution right away to concentrate at the tube's bottom and return it to a constant temperature. 1.2 To get the working concentration of the 1 mM storage solution, dilute it with culture medium or an appropriate buffer (like PBS). Note on recommended working solution concentration: Please make sure that the Green DND-26 working solution is ready for usage by adjusting its concentration to match the current circumstances. 2. 2.1 Suspension cells for cell staining: Centrifuge cells, add PBS, and wash twice for five minutes each time. Adherent cells: remove cells and add digested islets of cell material. Add PBS and centrifuge, then discard the supernatant. Wash twice, for five minutes each time. 2.2 After adding 1 milliliter of the Green DND-26 working solution, incubate for half an hour. 2.3 Discard the supernatant after centrifuging at 400 g for three to four minutes at 4°C. 2.4 Wash the cells twice with PBS, giving them five minutes each time. 2.5 Re-suspend the cells in 1 milliliter of PBS or serum-free water, and examine them using a flow cytometer or fluorescence microscope. Storage temperature: -20°C, shielded from light
In vitro, Green DND-26 is used for live-cell imaging and flow cytometry to label and visualize lysosomes. It is suitable for observing lysosomal internal biosynthesis and related pathogenesis. The dye can be used to study lysosomal trafficking, acidification, and function in various cell types. It is commonly used in combination with other fluorescent probes for multicolor imaging experiments. The recommended working concentration is 50-100 nM. |
| ln Vivo |
In vivo, Green DND-26 is primarily used for ex vivo applications rather than direct in vivo administration. It can be used to label lysosomes in cells isolated from tissues or in tissue sections for histological analysis. The dye has been used to study lysosomal dynamics in zebrafish and other model organisms. However, its use in live mammals is limited due to potential toxicity and rapid clearance. Its primary applications are in vitro for cell biology research.
|
| Enzyme Assay |
For in vitro fluorescence characterization, Green DND-26 is dissolved in appropriate buffer, and its absorption and emission spectra are measured using UV-visible and fluorescence spectrophotometers. The maximum excitation is at 504 nm and emission at 511 nm. The pH-dependent fluorescence properties can be characterized by measuring fluorescence intensity in buffers of varying pH to confirm the lysosomal targeting mechanism.
|
| Cell Assay |
For live cell staining, cells are cultured on coverslips or in imaging dishes. The Green DND-26 stock solution (1 mM) is diluted to a working concentration of 50-100 nM in pre-warmed culture medium or appropriate buffer. Cells are incubated with the working solution for 30 minutes at room temperature. Cells are then washed twice with PBS for 5 minutes each. Labeled cells are imaged using fluorescence microscopy with FITC filter sets (excitation ~504 nm, emission ~511 nm) or analyzed by flow cytometry.
|
| Animal Protocol |
For in vivo applications, Green DND-26 is not typically administered systemically to mammals. In zebrafish or other small model organisms, the dye can be added to the water or injected into embryos for live imaging of lysosomal dynamics. Cells isolated from tissues can be stained ex vivo with Green DND-26 following the cell staining protocol described above, then analyzed by flow cytometry or microscopy. Tissue sections can also be stained with the dye for histological analysis of lysosomal distribution.
|
| ADME/Pharmacokinetics |
Green DND-26 is soluble in DMSO (125 mg/mL, 345.08 mM). The compound should be protected from light during handling and storage to prevent photobleaching. Storage is recommended at 4°C for long-term stability, and at -80°C for 6 months or -20°C for 1 month in solvent. The dye is for research use only and is not intended for human or veterinary use.
|
| Toxicity/Toxicokinetics |
Toxicological data for Green DND-26 have not been extensively reported, as it is a fluorescent probe rather than a therapeutic agent. At the low concentrations used for cell staining (50-100 nM), the dye is generally well-tolerated by cells for short-term experiments. Higher concentrations or prolonged exposure may be cytotoxic. The compound is for research use only and is not intended for human use. Standard laboratory safety precautions should be followed when handling this compound.
