Unlike paraffin-embedded tissues, frozen sections are required because the organic solvents used in the staining process would dissolve the paraffin wax. It is critical to understand that this technique specifically targets neutral fats, including triglycerides and cholesterol esters, while leaving other cellular components unstained.
Oil Red O Staining Protocol Step By Step
This specific chromogenic method relies on the absorption of the fat-soluble dye Oil Red O into lipid droplets, providing a vivid red contrast against a pale background. Researchers can define specific regions of interest within the tissue, such as atherosclerotic plaques or hepatocytes, and calculate the percentage of area occupied by lipid droplets.
Image analysis software plays a crucial role in this process by converting the stained sections into high-contrast images for accurate measurement. Researchers can define specific regions of interest within the tissue, such as atherosclerotic plaques or hepatocytes, and calculate the percentage of area occupied by lipid droplets.
Oil Red O Staining Protocol Step By Step
Oil Red O staining is a fundamental histological technique used to visualize and quantify neutral lipids within frozen tissue sections. It is important to note that oil-based mounting media must be avoided as they can dissolve the Oil Red O dye, leading to fading and loss of the staining signal.
