Description and Uses

Nile Red is an aphotostable and lipophilic stain for intracellular lipids and hydrophobic domains of proteins and also for staining of lysosomal phospholipid inclusions.

Nile red is a lipophilic stain. It stains intracellular lipid droplets. Nile red is also intensely fluorescent, with a strong yellow-gold emission if included into a lipid-rich environment.
