Chlorazol black fungal stain procedure.

Chlorazol black E is a stain with a high affinity for chitin, a unique structural polysaccharide (a homopolymer of -[1,4]-linked D-N-acetylglucosamine), which is found in fungal cell walls but not in vertebrate tissues; chlorazol black E stains the cell walls of filamentous fungi and of yeasts a blue-black color.13 A chlorazol black E-stained wetIt also helps in distinguishing fungal bodies from artefacts due to chitin staining.
