ABSTRACT:
Disclosed is a nucleic acid hybridization assay composition for detecting the presence of 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 DAN-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.
