DMACA is an histological dye used to detect indole production in cells. It is used for the rapid identification of bacteria containing tryptophanase enzyme systems.

It is also particularly useful for localization of proanthocyanidins compounds in plants, resulting in a blue staining. It has been used for grapevine fruit^[1] or for legumes foliage^[2] histology.
