Description

Description générale

Oil Red O is a lysochrome. It is used to stain and visualise general localization of fats.

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.

Application

Oil Red O has been used for the staining of lipid droplets and lipid-containing vacuoles in cells.

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

Adéquation

Certified for use as a fat stain in Churukian′s modification of the method of Lillie and Asburn.
