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

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

After UV irradiation of rapidly frozen solutions of N,N,N',N'-tetramethylbenzidine (TMB) in dilute aqueous micellar cetyltrimethylammonium bromide at 80 K, the ESR signal corresponding to the TMB+ cation was detected indicating photoionization. This signal was monitored as a function of time
