Abstract

Reagents, kits and methods for detecting biological molecules by energy transfer from an activated chemiluminescent substrate to an energy acceptor dye such as a J-aggregated dye are described.

Claims

1. An article of manufacture comprising;

a support comprising a surface;

a chemiluminescent enhancing material on the surface of the support;

an energy acceptor dye on the surface of the support;

one or more biomolecular probes on the surface of the support; and

a molecular filter on the surface of the support;

wherein the molecular filter is selected from the group consisting of hemoglobin, dabcyl, DPX and DNP C2 Amine and wherein the energy acceptor dye is a J-aggregated dye.

2. The article of claim 1, wherein the molecular filter is hemoglobin.

3. The article of claim 1, wherein the chemiluminescent enhancing material is a cationic homopolymer or copolymer comprising positively charged onium groups.

4. The article of claim 3, wherein the chemiluminescent enhancing material comprises poly(vinylbenzyldimethylbenzylammonium chloride) (BDMQ), poly(vinylbenzyltrimethylammonium chloride) (TMQ), poly(vinylbenzyltributylammonium chloride) (TBQ), poly(vinylbenzyltri(n-pentyl) ammonium chloride) (TPQ), poly(vinylbenzyltributylphosphonium chloride) (TB), poly(vinylbenzyltrioctylphosphonium chloride) (TO), two or more of any of the foregoing or a copolymer comprising one or more of the foregoing.

5. The article of claim 1, wherein the support is a particle.

6. The article of claim 1, wherein the support comprises latex, polystyrene, nylon, polyacrylamide or poly(styrenedivinyl benzene) beads.

7. The article of claim 1, wherein the J-aggregated dye is a cyanine dye.

8. The article of claim 1, wherein the one or more biomolecular probes comprise antibodies, polynucleotide, oligonucleotides, polypeptides, proteins, receptors, lectins or aptamers.

9. The article of claim 1, wherein the support has an anionic surface, the chemiluminescent enhancing material is a cationic homopolymer or copolymer on the support surface and the J-aggregated dye is an anionic dye on the cationic homopolymer or copolymer.

10. The article of claim 9, wherein the anionic dye is an anionic cyanine dye having the structure as set forth below:
