  • Patent number: 9040252
    Abstract: Method for increasing and regulating the emission of light from a chemiluminescent reaction including luminol, a peroxidase enzyme, an oxidant and an electron mediator (primary enhancer) through the use of an acylation catalyst (secondary enhancer) belonging to the class of N-azoles, i.e., a class of five-membered nitrogen heteroaromatic ring compounds containing at least one other atom of nitrogen. N-azoles, which are especially useful as secondary enhancers are imidazole, 1-methylimidazole, 1,2,3-triazole and 1,2,4-triazole. The invention also describes the use in diagnostic assays of chemiluminescent substrates containing said N-azoles, as secondary enhancers.
