Abstract: The invention relates to a method for the detection of oligonucleotides using anion exchange high performance liquid chromatography. Fluorescently labelled peptide nucleic acid oligomers, complementary to the oligonucleotide are hybridized to the oligonucleotides. Anion exchange high performance liquid chromatography is then performed and the hybridized moieties detected and quantitated. The invention also relates to a method for the simultaneous detection of both strands of an oligonucleotide in parallel from one sample, and a kit for use in qualitative and quantitative detection of one or two strands of an oligonucleotide.

Abstract: Provided herein is a method for detecting at least two distinct oligonucleotides of equal length in parallel from one biological sample, comprising the steps of providing a biological sample containing or suspected of containing oligonucleotides of interest; forming a hybridization mixture using at least two fluorescently labelled detection molecules with different surface charges; separating the detection molecules hybridized to the oligonucleotides by anion exchange HPLC; and detecting the hybridized detection molecule-oligonucleotide moieties by quantitative fluorescence readout. In a further aspect, a kit comprising at least two detection molecules is provided. In another aspect, provided herein is the use of at least two detection molecules with different surface charges for quantitatively detecting at least two distinct oligonucleotides of equal length in parallel from one biological sample.
