Abstract: A method for enhancing the conversion of a phenol substrate to a product by a peroxidase enzyme comprises the steps of reacting a conjugate comprising a detectably labeled phenol with a peroxidase enzyme in the presence of an enhancing reagent, the enhancing reagent comprising an inorganic salt, an organic compound having the formula wherein when X is B(OH)2, Y is I, or wherein when X is OH, Y is a halogen, or Q-R wherein Q is a linear or branched 1-12 heteroatom alkyl wherein tie heteroatoms are selected from C, N, O, and S, wherein the bonds connecting the heteroatom alkyl chain are single or double, wherein any carbon atom in the heteroatom alkyl chain optionally includes a substituent selected from —OH, —COOH, —NH2, and —SH, and wherein R is selected from —OH, —COOH, —NH2, and —CH3; or mixtures of the inorganic salt and the organic compound.

Abstract: A method for performing a peroxidase-based assay by reacting a peroxidase enzyme with a soluble organic p-hydroxyphenyl-containing compound having the formula: wherein Q is a linear or branched 1-12 heteroatom alkyl wherein the heteroatoms are selected from C, N, O, and S, wherein the bonds connecting the heteroatom alkyl chain are single or double, wherein any carbon atom in the heteroatom alkyl chain optionally includes a substituent selected from —OH, —COOH, —NH2, and —SH, and wherein R is selected from —OH, —COOH, —NH2, and —CH3; and converting the soluble organic p-hydroxyphenyl-containing compound into a stable insoluble product which becomes highly fluorescent after illumination, upon excitation.

Abstract: 4-(4-hydroxystyryl) pyridine-containing compounds are disclosed as substrates for use in assays. Also, a method for detecting or quantitating an analyte is provided which includes reacting an enzyme with a 4-(4-hydroxystyryl) pyridine-containing compound to form a reactive intermediate wherein the reactive intermediate deposits covalently on a surface by binding to a receptor, wherein deposited reactive intermediates either directly or indirectly through a label generate a signal which can be detected or quantitated.
