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

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

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

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

An enzyme immunoassay for detection of hepatitis B surface antigen based on the use of 3 monoclonal antibodies (mAbs) was developed: an IgM as capture and 2 IgG1 for detection. The system biotin-streptavidin was compared with direct conjugation of mAbs
