Abstract

Abstract A polymer-bound linkable dye comprising a) a water-soluble polymer backbone, b) a dye covalently bound thereto, and c) functional groups which enable the polymer-dye to link covalently with biological materials, in which the water-soluble polymer backbone is a copolymer which contains arcylamide, methacrylamide, N-C 1 -C 4 alkyl(meth)acrylamide, N,N-C 1 -C 4 dialkylacrylamide, N-vinylpyrrolidone, N-vinylpiperidone, N-vinylcaprolactam, N-vinylformamide, N-vinylacetamide, N-vinyl-N-methylacetamide, N-vinyl-O-methylurethane, ethene or vinylmethylether as nonionic monomer blocks. The polymer-bound dye can be linked to a biologically active material such as an antibody or nucleic acid and used analytically.
