摘要:
The present invention relates to means for the detection and characterization of nucleic acid sequences, as well as variations in nucleic acid sequences. The present invention also relates to methods for forming a nucleic acid cleavage structure on a target sequence and cleaving the nucleic acid cleavage structure in a site-specific manner. The structure-specific nuclease activity of a variety of enzymes is used to cleave the target-dependent cleavage structure, thereby indicating the presence of specific nucleic acid sequences or specific variations thereof.
摘要:
Disclosed are a method and a corresponding composition of matter for detecting single nucleotide polymorphisms. The composition of matter includes a metal substrate, a probe oligonucleotide immobilized on the substrate; and an upstream oligonucleotide either immobilized on the substrate or in a solution in contact with the substrate. The probe oligonucleotide and the upstream oligonucleotide participate cooperatively in an invasive cleavage reaction when the substrate is contacted with a cleavage agent and a target nucleic acid. Under proper reactions conditions, the probe oligonucleotide, the upstream oligonucleotide, the target nucleotide, and the cleavage agent cooperative result in the formation of a cleavage product at or near the location of a single nucleotide polymorphism of interest.
