Description

Application

Azure A chloride has been used for the staining of polyacrylamide gel to analyse the bovine lung heparin digestion by heparinase I. It has been used for the determination of the sulphated groups content in polysaccharides.

Actions biochimiques/physiologiques

Azure A is a basic cationic dye. 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. It is a main component of the azure B/polychromed methylene blue – eosin stains family, also referred to as the Romanowsky stain.

Attention

Handle and store under argon. Glove bag item.
