Product Image-APPC252908.1608

Kovac's indole reagent for microbiology

Catalog Number: (APPC252908.1608)
Supplier: PanReac AppliChem
Description: A reagent for the detection of indole-positive and indole-negative microorganisms. Some microorganisms can cleave tryptophan which is especially abundant in trypticalle digested peptone to give pyruvic acid, ammonia and indole. Indole then reacts with 4-dimethylaminobenzaldehyde to form a dark red dye. As tryptophan also gives a colour reaction with 4-dimethylaminobenzaldehyde, it must be separated from the indole. This is achieved by selectively extracting indole with butanol.
