| Application: | Oil Red O has been used for the staining of lipid droplets and lipid-containing vacuoles in cells. |
| Application: | Oil Red O has been used: • for staining liver sections in histological analysis • for the quantification of lipids in cells • to stain aorta to examine atherosclerotic lesions |
| General description: | Oil Red O is a lysochrome. It is used to stain and visualise general localization of fats. |
| General description: | Oil Red O stains lipid materials and the lipids take red-orange color. 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, since alcohol fixation removes lipid. |
