<p>A nucleic acid hybridization assay wherein the hybrid formed between the polynucleotide sequence to be detected and the probe is immobilized by binding of an immobilized or immobilized form of an antibody reagent selective for binding such hybrid. Preferred antibody reagents are selective for DNA?RNA or RNA?RNA hybrids or for intercalated duplexes. The immobilized hybrid is detected preferably by use of a labeled form of a second such antibody reagent or a labeled form of the probe. The method dispenses with the need to immobilize either the probe or sample nucleic acids and permits hybridization to proceed between the sequence to be detected and the probe in solution, resulting in rapid rates of hybridization.</p> |
