Descripción

General description

Methylene blue is a compound that occurs as crystals or crystalline powder, having a bronze-like luster. It is soluble in water, chloroform and partially soluble in alcohol. It is a photoactive dye, which is a member of phenothiazine family.

Application

Methylene blue has been used:

• to stain vaginal cells
• for the preparation of protein aqueous ink
• to evaluate cell survival by staining

Biochem/physiol Actions

Methylene blue is used as a bacteriologic stain or dye and indicator. It mediates the inactivation of enveloped viruses in plasma, when exposed to visible light. It is an inhibitor of nitric oxide synthase and guanylate cyclase. It also plays a key role in medicine as an antimalarial agent, reducing agent in methemoglobinemia and inducer of apoptosis in cancer cells.

Suitability

Certified for use in Mallory′s phloxine-methylene blue stain; Levine & Black stain for bacteria in milk; Wright stain for blood smears.
