Chemical Properties
green to dark brown powder
Uses
Biological stain.
Uses
For staining cell granules and tissues
Definition
ChEBI: An organic chloride salt having 3-amino-7-(dimethylamino)phenothiazin-5-ium as the counterion. It is used in making azure eosin stains for blood smear staining.
Biological Activity
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.
Purification Methods
Azure A has been twice recrystallised from H2O and dried at 100o/1hour in an oven. [Beilstein 27 III/IV 5151.]
