Energy transfer hybridization assay composition
First Claim
1. A nucleic acid hybridization assay composition for detecting the presence or absence of a target oligo- or polynucleotide in a sample, which composition comprises:
- a solid matrix having at least one surface to which is fixed or immobilized a first intercalator capable of binding dsDNA, dsRNA or DNA-RNA hybrids;
a second intercalator, which may or may not comprise at least one fluorophore, said second intercalator or said fluorophore, each acting as either an energy donor or an energy acceptor; and
an oligo- or polynucleotide probe which is specifically hybridizable with the target oligo- or polynucleotide and has directly or indirectly bound thereto as least one lanthanide metal or at least one fluorophore, each acting as either an energy donor or an energy acceptor.

Abstract
Disclosed is a nucleic acid hybridization assay composition for detecting the presence or absence of a target oligo- or polynucleotide in a sample. The composition comprises: a solid matrix having at least one surface which is substituted with a first intercalator capable of binding dsDNA, dsRNA, or DNA-RNA hybrids; a second intercalator, which may or may not comprise at least one fluorophore, said intercalator or said fluorophore, each acting as either an energy donor or an energy acceptor; and an oligo- or polynucleotide probe which is specifically hybridizable with the target oligo- or polynucleotide and has directly or indirectly bound thereto, at least one lanthanide metal chelate or at least one fluorophore, each acting as either an energy donor or an energy acceptor. Also disclosed are a method and kit for its use.
