Polynucleotide capture assay employing in vitro amplification

Abstract From the Canadian patent

An analyte polynucleotide strand having an analyte sequence is detected within a sample containing polynucleotides by contacting the analyte polynucleotide with a capture probe under hybridization conditions, where the capture probe has a first binding partner specific for a solid-phase second binding partner. The resulting duplex is then immobilized by specific binding between the binding partners, and non-bound polynucleotides are separated from the bound species. The analyte polynucleotide is optionally displaced from the solid phase, then amplified by PCR. The PCR primers each have a polynucleotide region capable of hybridizing to a region of the analyte polynucleotide, and at least one …
