ABSTRACT:
A method for the isolation and quantitative detection of a selected single-stranded target polynucleotide from solution. The target polynucleotide is hybridized in solution to a single-stranded mediator polynucleotide, a probe polynucleotide, and an immobilized polynucleotide sequence. The sequence of the mediator polynucleotide comprises a first sequence complementary to a first portion of the target polynucleotide sequence and a second nucleotide sequence complementary to a portion of a single-stranded immobilized polynucleotide sequence. The probe polynucleotide, which carries a detectable label, is complementary to a second portion of the necleotide sequence of the target. The immobilized polynucleotide is immobilized by attachment to a solid support, and, through hybridization to the mediator polynucleotide, functions to immobilize the entire immobilized polynucleotide/target polynucleotide/probe polynucleotide "sandwich".
