Methods for reducing non-specific priming in DNA detection

摘要

A method for detecting a target nucleic acid, which method includes the steps of (i) amplifying the target nucleic acid to obtain an amplification product using a polymerase, a first primer with or without a segment noncontiguous to a first priming sequence, and a second primer with or without a segment noncontiguous to a second priming sequence in the presence of an oligonucleotide which is incapable of acting as a primer for the polymerase, wherein the oligonucleotide has at least 5 consecutive nucleotides fully complementary to at least 5 consecutive nucleotides of the first primer; and (ii) detecting the presence of the target nucleic acid by monitoring the amplification thereof.
