Abstract

Provided is a ultra-high-sensitivity assay in which the assay can be made on a commonly used assay apparatus such as an absorptiometer and a plate reader or with naked eyes. The high-sensitivity assay in which the assay can be made on a commonly used assay apparatus or with naked eyes can be provided by combining an enzyme cycling method using thio-NAD(P) as a coenzyme, a labeling enzyme and a substrate for the labeling enzyme optimally, and by amplifying thio-NAD(P)H, which is a signaling substance, exponentially and then quantifying the thio-NAD(P)H colorimetrically.
