Beschreibung

General description

Chlorazol Black has strong affinity for cellulose and chitin. In plant tissues, it helps to differentiate between cellulose and lignin. It also helps in distinguishing fungal bodies from artefacts due to chitin staining. It is also used as an auxiliary stain for chromosomes.

Application

Chlorazol Black has been used to monitor the infection of mycorrhizal Allium porrum in plant roots. It has also been used for the staining of copepods.
