Abstract
It is an object of the present invention to provide a luminescent polymer that is useful as a luminescent signal probe for labeling and detecting a target substance at high sensitivity in bioassay, and to provide the application of said luminescent polymer to bioassay. The luminescent polymer of the present invention comprises at least one biotin covalently attached to a polymer that includes monosaccharide or amino acid as a constituent monomer covalently attached to a luminescent substance. Preferably, two or more biotins are attached. Examples of the above-mentioned luminescent substance include cyanoisoindoles, luminols, and acridinium esters, and examples of the polymer include polysaccharides, polyamino acids, peptides, polypeptides, and proteins.
