General description

Oil Red O stains lipid materials and imparts red-orange color to the lipids. It also marks vacuoles, particularly observed in ALL-L3 (acute lymphoblastic leukemia) or Burkitt′s lymphoma/leukemia. Oil Red O staining is done on fresh samples, as alcohol fixation removes lipids.

Application

Oil red O solution has been used to stain neutral lipids and adipocytes and to visualize fat droplets in fibroblasts.
Oil red O is a lysochrome (fat-soluble dye) diazo dye used for staining of neutral triglycerides and lipids on frozen sections and some lipoproteins on paraffin sections. In histology, a supersaturated solution of oil red O in isopropanol may be used to stain fat in tissue.
