Vue d’ensemble

Sudan dyes are more soluble in lipids than in solvents. When the dye comes into contact with lipid-containing specimens, a large amount of dye partitions into lipid structures, staining these structures red. Lipid-soluble dyes such as Sudan dyes, Oil Red O and Nile blue are commonly used to visualize lipids.

Sudan IV stains suberized and cutinized cell walls, fats, volatile oils, resins and other substances red or light red, and serves as a fat stain.

Instructions for Use:

1. Fix in 4% neutral formalin for 24 h.

2. Rinse with water for 10 min.

3. Blot moisture from the tissue.

4. Incubate in Sudan IV staining solution for 5–15 min.

5. Differentiate with 70% ethanol. Optimal result: adipose tissue appears orange-yellow to light red while other tissues remain unstained.

6. Rinse and soak in water to remove excess stain.

7. Mount sections and examine under a microscope.

Staining Results:

Fat: Orange-yellow to light red

Precautions:

1. It is recommended to perform a preliminary test with 1–2 samples when using this reagent for the first time.

2. For personal safety, wear protective equipment such as a lab coat and gloves before handling reagents.
