Acriflavine hydrochloride

In living mice, acriflavine hydrochloride has been used in the confocal laser endomicroscopy to check the crypt structure in mucosa. It has also been used in Neurospora strain selection by checking the acriflavine resistance.


Acriflavine hydrochloride is a fluorescent dye. It is used as a topical contrast agent. It mainly stains nuclei and is applied to tissues before microscopy.


A mixture of 3,6-diamino-10-methylacridinium (acriflavin) and 3,6-diaminoacridine (proflavin).
