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

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

Polydisulfides of urea (PDSU), thiourea (PDSTU), biuret (PDSB), and gallic acid (PDSG) and their monomer analogues (urea, biuret, and gallic acid) inhibited (in a competitive manner) tetramethylbenzidine (TMB) peroxidation catalyzed by ferritin in 0.1 M acetate buffer, pH 4.2, containing

Photoionization of hydrophobic probes has been developed in micelles or synthetic vesicles. Studies of the yields, compartmentation, and lifetimes of the photo-produced charged species have gathered reliable information on the interfacial and structural properties of these assemblies. Such an approach
