Oil Red O is suitable as a lipid and lipoprotein stain on cellulose acetate. It is one of the diazo dyes used for staining of neutral triglycerides and lipids. It is used to analyze muscle fibers. It acts as an agent that stains lipids, muscle fibers and alveolar macrophages. Further, it is also used as marking dye. It is an active component of red colored smokes in pyrotechnics.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
