How do you make a Sudan 3 solution?
Sudan III stain solution: Dissolve 0.5 g of dye in 70 ml of ethanol and 30 ml of water, using a warm water bath, and filter. Ethanol is HIGHLY FLAMMABLE (see Hazcards 32 and 40). Label the solution HIGHLY FLAMMABLE. Wear safety goggles to prepare.
What is Sudan III solution?
Sudan III is a lysochrome (fat soluble dye) predominantly used for staining triglycerides in animal. tissues (frozen sections), but it may also stain some. protein bound lipids in paraffin sections.1 It is also. used by botanists together with Light Green SF.
How do you make Sudan Red solution?
Working Sudan III stain: • Dilute 6 ml of saturated Sudan III dye with 4 ml of distilled/demineralized water. Let it set for 5-10 minutes. Filter the solution.
What is the chemical formula of Sudan IV solution?
For staining purposes, Sudan IV can be made up in propylene glycol. Alternatively, authors have reported using the dye saturated in isopropyl alcohol, 95% ethanol, or 0.05% by weight in acetone:ethanol:water (50:35:15)….Sudan IV.

How do you use Sudan III to test for lipids?
Sudan Test for Fats Sudan III dissolved in ethanol is allowed to interact with the lipids bound to a filter, then when the filter is washed with water the water will not permit Sudan III bound to the lipids to escape. Consequently, spots containing lipids will appear orange against a pink background.
How do Lysochromes work?
A lysochrome is a soluble dye used for histochemical staining of lipids, which include triglycerides, fatty acids, and lipoproteins. Lysochromes such as Sudan IV dissolve in the lipid and show up as colored regions.
Is Sudan 3 and Sudan 4 the same?
NOTE: Sudan III will give a darker orange-red or red color and is more stable in alcohol than Sudan IV. 1. Balows, A., et al., 1991.
Is Sudan III hydrophobic or hydrophilic?
hydrophobic
A relatively polar molecule (e.g., acetone, acetonitrile, formamide, methanol, 1-propanol or tetrahydrofuran) can be used as electroosmotic flow marker, and usually a highly hydrophobic, neutral compound such as Sudan III, Sudan IV, dodecanophenone, Orange OT, or Yellow OB as micelle marker.
What is Sudan IV solution?
Sudan IV Stain is used to detect fat in feces, urine and tissues. Patients demonstrating fat in stool (i.e., steatorrhea) may have a correlation to pancreatic diseases or other fat absorption diseases.
What is the Sudan IV reagent?
Sudan IV is a hydrophobic azo dye. It stains triglycerides and imparts an intense red color. The dye does not stain lipid droplets or phospholipids.
