Nile Red

Nile red (Nile blue oxazone) is a lipophilic stain. Nile red has environment-sensitive fluorescence. Nile red is intensely fluorescent in a lipid-rich environment while it has minimal fluorescence in aqueous media. Nile red is an excellent vital stain for the detection of intracellular lipid droplets by fluorescence microscopy and flow cytof uorometry. Nile red stains intracellular lipid droplets red. The fluorescence wavelength is 559/635 nm[1].
