Usage

Description

OIL RED O is a bis(azo) compound that is 2-naphthol substituted at position 1 by a 4-[(2,5-dimethylphenyl)diazenyl]-2,5-dimethylphenyldiazenyl group. It is a fat-soluble dye predominantly used for demonstrating triglycerides in frozen sections and for staining of protein-bound lipids in paraffin sections.

Uses

Used in Medical and Scientific Research:
OIL RED O is used as a staining agent for visualizing and identifying lipids, particularly triglycerides, in tissue samples. This application is crucial in medical and scientific research for studying various aspects of lipid metabolism, storage, and related diseases.
Used in Histopathology:
In histopathology, OIL RED O is used as a staining agent for highlighting lipid-rich areas in tissue samples. This helps pathologists to differentiate between normal and abnormal tissue, as well as to identify specific types of cells and tissues that may be affected by lipid-related conditions.
Used in Cell Biology:
OIL RED O is used as a vital stain in cell biology to detect and quantify lipid droplets within cells. This application is particularly useful in studying the formation, storage, and metabolism of lipids in various cell types, as well as in assessing the effects of drugs or other treatments on cellular lipid content.
Used in Analytical Chemistry:
In analytical chemistry, OIL RED O is used as a colorimetric reagent for the quantification of lipids in various samples, such as food products, pharmaceuticals, and cosmetics. This application allows for the accurate measurement of lipid content, which is essential for quality control and product development in these industries.
