Abstract

This invention provides fluoroassay which comprises labeling analyte molecules with a fluorescent material having a nucleic acid portion stained with a sufficient number of fluorochrome molecules so as to be measurable as fluorescent spots, and a reactive group binding to the analyte molecule specifically, immobilizing the labeled analyte on a solid phase, and counting the number of fluorescent spots. The nucleic acid portion of the fluorescent labeling material is a double-stranded or single-stranded nucleic acid, and the staining with the fluorochrome molecules is performed with intercalating type, minor groove binding type, or covalently binding to the nucleic acid type.
