General description

Safranin O is a metachromatic, cationic dye. It is used as a counterstain in Gram staining. The stain colors Gram-negative bacteria pink to red and has no effect on Gram-positive bacteria. It is also used to assess glycosaminoglycans (GAGs) in cartilage. The dye imparts an intense red to GAGs. It easily binds to polyanions.

Application

Safranin O has been used in the staining of extraocular muscle mesenchymal stem cells (EOM-MSC) for the detection of cartilage, mucin and mast cell granules It has also been used as a mediator dye in cytochrome P450 spectral assay.
Safranin O has been used to stain matrix proteoglycans to study cartilaginous tissue structural integrity in mice. It has also been used to stain chondrogenically differentiated human bone marrow stromal cells.

Suitability

Certified as a stain for chromosomes in the Flemming triple stain; to stain gram negative bacteria in the Gram stain procedure; Safranine-fast green FCF stain for plant cells.
