Descrição geral
Oil Red O is a lysochrome.[1] It is used to stain and visualise general localization of fats.[2]
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.[3][4]
Aplicação
Oil Red O has been used for the staining of lipid droplets and lipid-containing vacuoles in cells.[5][6]
Oil Red O has been used:
for staining liver sections in histological analysis[7][8][9]
for the quantification of lipids in cells[10][11][12]
to stain aorta to examine atherosclerotic lesions[13]
Adequação
Certified for use as a fat stain in Churukian′s modification of the method of Lillie and Asburn.
