Fat or lipid dyes, such as the Sudan and Nile series, typically stain by dissolving the dye into a solvent with low solubility, followed by further dilution with water for use in most staining protocols. When the dye encounters a fat or lipid, it moves from the solvent with low solubility to the solvent with higher solubility. Nile Red is soluble in DMF, DMSO, heptane, xylene, 1% in acetone, and 0.1% in ethanol. There is no specific procedures for staining nanoparticles. However, if the nanoparticles contain a fat or lipid component, Nile Red is expected to work. As for the particle size in solution, there is no available information.

General description
Nile Red is a phenoxazone dye. It is an important stain, which is used to detect intracellular lipid droplets and proteins. Nile Red detects lysosomes and lysosome-related organelles, like gut granules in C. elegans intestinal cells. It exhibits strong fluorescence enhancement and is used for staining SDS (sodium dodecyl sulphate) gels.
Application
Nile Red has been used:
- as a fluorescent dye for staining fat by confocal scanning laser microscopy (CSLM)
- to label nanoparticles (NPs)
- for lipid analysis

Can the crystal form of Nile Red be used in the same way as the powder form, specifically in terms of using acetone to dissolve and create working solutions?
1 answer-
The form of the dye, whether as a powder or crystals, should not impact the process of reconstituting Nile Red or most other dyes. For product 72485, both the powder and crystal forms have the same solubility specification. Therefore, either form is acceptable. It's advisable to first use the solvent recommended in a published procedure if following one.
