A method of enhancing a luminescent reaction, luminometric assay and kits for use in the same

摘要

A chemiluminescent reaction, which may be utilized for immunoassay, carried out by reaction of 2,3-dihydro-1,4-phthalazinedione or its derivative, a peroxidase, and an oxidant, is enhanced by conducting it in the presence of a phenolic compound such as (4-cyanomethylthio)phenol. Especially, it is preferred that (4-cyanomethylthio)phenol is added to each of luminol, horseradish peroxidase, and a hydrogen peroxide to provide a significantly enhanced and stabilised luminescent reaction.
