Short Description::
Long Description::
Sudan IV is a lysochrome (fat-soluble dye) diazo dye used for the staining of lipids, triglycerides and lipoproteins on frozen paraffin sections. It has the appearance of reddish brown crystals with melting point 199 °C and maximum absorption at 520(357) nm.
Application::
Sudan IV is lipophilic diazo dye, very similar to Sudan III. It is primarily used in Sudan IV staining method or in Churukian's variety of Lillie-Ashburn method in which it replaces Oil Red O. Those methods are used for staining lipids, triglycerides and lipoproteins on frozen histology sections.
Dose::
The Sudan IV test will test positive for lipids. The test procedure involves adding a few drops of Sudan IV to the test solution. Sudan IV is a dye that will stain lipids. If no lipids are present then the dye will sink to the bottom of the test tube.
Note::
Sudan Black B is a diazo dye used for staining of neutral triglycerides and lipids on frozen sections and some lipoproteins on paraffin sections. It has the appearance of a dark brown to black powder with maximum absorption at 596-605 nm and melting point 120-124 °C. It stains blue-black
