General description

Nile Red is a lipophilic fluorescent benzophenoxazone dye that is metachromatic and solvatochromic.PMID 34454386 It is an uncharged hydrophobic molecule with the ability to stain and visualize lipid droplets in cells and tissues.PMID 3442318 It functions as a fluorescent probe for intracellular lipids and hydrophobic domains of proteins. This dye is fluorescent in all organic solvents. Its fluorescence colors range from golden yellow to deep red.PMID 3972906

Application

Nile red is widely employed in studies related to lipid metabolism, lipid droplet dynamics, lipid accumulation in cells or tissues, and lipid-based drug delivery systems. Its other applications include:
  • identification of microplastics in routine analysis of biological samples.PMID 34454386
  • detection of lysosomes and lysosome-related organelles, like gut granules in C. elegans intestinal cells.PMID 22226526
  • it exhibits strong fluorescence enhancement and is used for staining SDS (sodium dodecyl sulphate) gels.

Biochem/physiol Actions

Nile Red is lipophilic in nature and exploits the hydrophobic properties of molecules such as lipids and plastics that fluoresce when excited with certain wavelengths, facilitating quantification and identification.[1]

Questions

  1. How should n3013 be dissolved and diluted for lipid staining?

    1 answer
    1. There has not been any conduct suitability testing for Nile Red. Please see the following for an article that may offer information; J. Histochem. Cytochem. 35:619-621 reference.
      To perform the staining, a stock solution of Nile red was prepared by dissolving 10 mg of Nile red in 10 ml of acetone, which was then stored in the refrigerator protected from light. The sections were fixed in 1% glutaraldehyde in PBS for 5 minutes and washed in PBS three times for 2 minutes each. The staining solution was then prepared by diluting 100 ul of the stock solution in 1 ml of PBS. The sections were covered with this solution for 20 minutes at room temperature, then briefly washed in PBS and mounted in 75% glycerol in PBS. Other sections were incubated with solutions containing 50, 10, and 1 ug and 100 ng of Nile red per ml. The sections were examined with a filter set for fluorescein fluorescence (450-500 nm band pass excitation filter, a 510 nm center wavelength chromatic beam splitter, and a 528 nm long-pass barrier filter) and were photographed.
