Beschreibung

Allgemeine Beschreibung

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.

Anwendung

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.

Eignung

Zertifiziert für die Flemming'sche Dreifachfärbung von Chromosomen, Färbung gramnegativer Bakterien bei der Gramfärbung, Safranin-Echtgrün FCF-Färbung von Pflanzenzellen.
