Application

4-(Dimethylamino)benzaldehyde (DMAB or Ehrlich’s reagent) has been used as a color reagent for the determination of hydroxyproline level.It forms colored condensation products (Schiff bases) with pyrroles and primary amines. DMAB is also suitable as a reagent to develop latent fingermarks on paper surfaces yielding impressions that are both colored and photoluminescent.

Duchenne muscular dystrophy was initially described as a myosclerosis because of the conspicuous progression of interstitial fibrosis. Using the mdx mouse homologue, we have shown previously that the accumulation of intramuscular collagen is profoundly influenced by the presence or absence

A simple colorimetric method for the differentiation of indoleacetic acid (IAA) and indolebutyric acid (IBA) in plant samples is described. The color change is based upon the reaction between the auxins and p-(dimethylamino)benzaldehyde (PDAB, Ehrlich reagent) following the electrophilic substitution

A method for estimating the total limonoid aglycone and glucoside concentrations in Citrus samples in terms of limonin and limonin glucoside equivalents is presented. The method consists of extraction followed by colorimetric quantification. The colorimetric quantification was based on the

The structures of pyrrolic forms of cross-links in collagen have been confirmed by reacting collagen peptides with a biotinylated Ehrlich's reagent. This reagent was synthesized by converting the cyano group of N-methyl-N-cyanoethyl-4-aminobenzaldehyde to a carboxylic acid, followed by conjugation with

The Ehrlich reaction was optimized to determine pyrrolized proteins produced as a consequence of lipid peroxidation and oxidative stress. The procedure consisted of the treatment of the modified protein with p-(dimethylamino)benzaldehyde at a controlled acidity and temperature, and the determination
