ABSTRACT:
A method for determining the presence of a polynucleotide analyte in a sample suspected of containing the analyte is disclosed. The method comprises combining in an assay medium the sample and first and second polynucleotide reagents complementary to the analyte. Each of the first and second reagents hybridize with a different region of the analyte. The first reagent contains means for rendering the first reagent non-covalently polymerizable. The second reagent contains means for rendering the second reagent detectable. The sample and the first and second reagents are combined in the assay medium under conditions for polymerizing the first reagent wherein the second reagent becomes bound to the polymerized first reagent only when the analyte is present in the sample. A determination is then made as to whether the second reagent has become bound to the polymerized first reagent. The method has broad application for determining the presence of a polynucleotide analyte such as DNA, RNA, the genomes of viruses, bacteria, molds, fungi, and fragments thereof, and the like. Preferred means for rendering the first reagent non-covalently polymerizable includes a repeating oligonucleotide sequence covalently bound to the first reagent.
