What does the Sudan test test for?
In summary, based on the examination of purified lipids in a predefined matrix, we found that the Sudan stain is a specific test for detecting triglycer- ide and fatty acid. The neutral fat stain identifies triglyceride. Moreover, at an appropriate pH, the neutral fat stain also identifies fatty acid.

What does Sudan red stain?
Sudan staining is the use of Sudan dyes to stain sudanophilic substances, usually lipids. Sudan lysochromes (Sudan II, Sudan III, Sudan IV, Oil Red O, and Sudan Black B) are used. Sudan dyes have high affinity to fats, therefore they are used to demonstrate triglycerides, lipids, and lipoproteins.
What does Sudan black stain?
Black Sudan B is used for the staining of a wide variety of lipids such as phospholipids, steroles and neutral triglycerides. Black Sudan B is not lipid specific like other Sudan dyes and can also be used for chromosome staining, Golgi apparatus and leukocyte granules.
What is the use of Sudan red 3 solution?
