Oil Red O Stain
Oil red is intended for the staining of neutral fat.
Staining of lipids is believed to relate to the physical properties of solution or adsorption. Dyes exhibit a greater solubility in lipoid substances of frozen tissue than that in original solvents. So during staining, dyes will migrate into lipids from organic solvents resulting in lipid staining.
