Abstract
The invention provides an assay by which detection and/or quantitation of adenyl group-containing substances can be performed simply, with high sensitivity and high signal-to-noise ratio. In particular, the method provides an assay in which the chemiluminescence of a chemiluminescent substance, made by reacting a glyoxal derivative with an adenyl group in the substance to be detected/quantitated in the presence of a heteropolyacid or a heteropolyacid salt, is measured.
