ABOUT PRODUCT

What Is Safranine?

Safranine is a synthetic basic dye belonging to the phenazinium class of dyes. It is primarily used as a counterstain in Gram staining, where it stains Gram-negative bacteria pink/red, allowing easy differentiation from Gram-positive bacteria stained purple by crystal violet. Beyond microbiology, Safranine plays a crucial role in plant histology, animal tissue staining, and industrial coloration applications.

INDUSTRIAL APPLICATIONS

Applications Of Safranine

Safranine is extensively used in plant histology to stain lignified tissues such as xylem, sclerenchyma, and cuticles bright red. It is also used to highlight chitin in fungi and to stain cartilage, mucin, and mast cell granules.

In microbiology, Safranine is the standard counterstain in Gram staining procedures, helping in the identification of Gram-negative bacteria.

Safranine is used in cytological preparations to differentiate cellular structures and identify abnormalities in tissues.

The dye binds strongly to acidic proteoglycans, making it ideal for Safranin O staining of cartilage, useful in osteoarthritis research.

Safranine T serves as a redox indicator in titrimetric and electrochemical analysis.

Safranine is used as a leveling agent and brightener in the electroplating industry, providing uniform metal deposition.

The dye is used to color silk, wool, leather, and paper, providing brilliant red shades with good fastness.
