    DESCRIPTION

    General description

    Kovac′s reagent is prepared by mixing p-dimethylaminobenzaldehyde, isoamyl alcohol and concentrated hydrochloric acid.[1] For identification of an organism, the formation of Indole from a tryptophan substrate is a useful diagnostic tool. Indole production is a crucial test in identification of Escherichia coli. After incubation, adding the reagent will help in determination if Indole that has been produced. The reagent turns red when reacts with Indole.[2]

    Application

    In the presence of oxygen, some bacteria, like E.coli, are able to split tryptophan into indole and alpha-aminopropionic acid. This reagent is for detecting the indole and identify the indole-positive and indole-negative microorganisms.
    Kovac′s reagent may be used for spot test for determination of indole by saturating filter paper with the reagent.[3] It may also be used for initial spot test for determination of indole followed by quantification by spectrophotometric assay and HPLC-UV/Vis-MS/MS methods.[4]
