DETECTION OF NUCLEIC ACIDS BY FORMATION OF TEMPLATE-DEPENDENT PRODUCT

摘要

A method is disclosed for detecting a target polynucleotide sequence. The method comprises incubating an oligonucleotide with the target polynucleotide sequence and a nucleotide polymerase under isothermal conditions wherein at least one nucleotide is added to the 3'-terminus of the oligonucleotide to provide an extended oligonucleotide having the additional nucleotides. The presence of extended oligonucleotide is detected as an indication of the presence of the target polynucleotide sequence. The method has particular application to the detection of DNA.
