The mechanism of peroxidative N-dealkylation of alkylamines proceeds via one-electron oxidation to the iminium cation which reacts with water to give the N-hydroxymethyl derivative which decomposes to formaldehyde and the N-demethylated product. This reaction is normally inhibited by glutathione by

Quantitative microdilution plate hybridization was used to identify 22 Mycobacterium species. DNAs of clinical strains were rapidly extracted and labeled with photoreactive biotin. Labeled DNAs were distributed into wells of a microdilution plate in which reference DNAs had been immobilized.

The intra-axonal transport of horseradish peroxidase (HRP) has been used to trace the nodose ganglion and brain stem projections of a physiologically distinct nerve - the aortic depressor nerve - following electrophysiological identification. Tetramethyl benzidine (TMB) has been used as

Tetramethylbenzidine (TMB) histochemistry for retrogradely transported horseradish peroxidase (HRP) has been successfully applied in electron microscopical preparations in the guinea pig visual cortex. In ultrathin sections, the TMB--HRP reaction product appears as an accumulation of typical electron-dense crystals. These crystals
