Abstract

Tyrosine markedly attenuates the chemiluminescence output intensity from the 4โ€iodophenol enhanced chemiluminescence assay system in a manner consistent with competition between the amino acid and luminol for the 4โ€iodophenoxy radical. This effect provides the basis for a sensitive assay of tyrosine. Interference by the other amino acids has been assessed; major interference by cysteine can be removed by incubation with iodoacetic acid.

The intensity of 4-I-phenol-enhanced chemiluminescence from the luminol-H,O,-horseradish peroxidase system is markedly attenuated in the presence of low concentrations of non-enhancer phenols. Under the conditions studied, the effect is not associated with competition between 4-I-phenol and non-enha

The enhanced chemiluminescence reaction (ECL) was applied to the study of horseradish peroxidase (HRP) inactivation during the oxidation of p-iodophenol. Enzyme inactivation was shown to be the main reason for light decay in the course of the reaction. No individual effect of luminol and p-iodopheno

Light is emitted in systems containing N-chloramines or hypochlorite, H(2)O(2) and N-(4-aminobutyl)-N-ethylisoluminol (ABEI). The emission is enhanced by 4-iodophenol (PIP) in alkaline solution (1 mol/L NaOH), while at lower pH range (9-11) PIP is not only inactive but also its presence reduces chem
