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

Site-directed mutagenesis was used to produce a Synechocystis mutant containing a histidine tag at the C terminus of the CP 47 protein of Photosystem II. This mutant cell line, designated HT-3, exhibited slightly above normal rates of oxygen evolution and

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 tetramethylbenzidine (TMB) oxidation kinetics dependent on spleen ferritin (FERR) has been studied in TMB-FERR-H2O2 (1) and TMB-FERR-O2 (2) systems at pH 4.2 and 6.0. At TMB concentrations below 6 mM, the dependencies of the initial rate for protein oxidation
