Abstract
The invention relates to a method for the detection of natural or modified nucleic acids by their sequence specific hybridization with charge-modified oligonucleotide probes having charge-modifying groups attached to their backbones. The charge-modifying groups partially or fully neutralize the net negative charge of the backbone of the oligonucleotide probes or render them with a net positive charge. The charge-modified oligonucleotide probes may or may not be labeled, for example, with fluorescent, visible or near-infrared dye, with radioactive or stable isotopes, or with high specific affinity binding groups. The charge-modified oligonucleotide probes facilitate the separation of their hybrids with the targeted nucleic acids from the unhybridized probes or from any other components of the analyzed sample. They also allow for the modification and optimization of the properties of the hybrids with the targeted nucleic acids, such as melting temperature, chromatographic properties and off-target specificity.
