Chlorure de 3-amino-7-dimethylaminophénothiazine-5-ium

The combination of azure A and silver staining is used for the quantification of glycosaminoglycans in agarose gels. It is also used for the staining of chromosomes in the nucleus. Azure A is a main component of the azure B/polychromed methylene blue-eosin stains family, also referred to as the Romanowsky stain. Azure A is a basic cationic dye.


Azure A has been used to determine the amount of charged dextran sulfate in the nanoparticles for the study involving incorporation of heparin-binding proteins into preformed dextran sulfate-chitosan nanoparticles. Certified for use in Lillie′s modified Nocht′s method and the NCCLS method for blood smears.
