Oil Red O (ORO)
Used to stain lipids, lipid-containing vacuoles, and triglycerides to assess their morphology.This stain must be used on frozen sections, as paraffin processing dehydrates lipids.
Results: Lipids stain red. A counterstain can be used to visualize other structures, such as nuclei, which can be stained blue with hematoxylin.
