DMACA reagent
Encyclopedia
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 proanthocyanidin
s compounds in plants, resulting in a blue staining. It has been used for grapevine fruit or for legumes foliage histology.
Indole
Indole is an aromatic heterocyclic organic compound. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. Indole is a popular component of fragrances and the precursor to many pharmaceuticals. Compounds that contain an...
