SEQUENCE CONVERSION AND SIGNAL AMPLIFIER DNA HAVING POLY DNA SPACER SEQUENCES AND DETECTION METHODS USING SAME

摘要

Disclosed are methods for detecting a target nucleic acid in a sample. The methods include contacting said sample, in the presence of a polymerase and an endonuclease, with a sequence conversion oligonucleotide. Also disclosed are methods for detecting a target nucleic acid in a sample in which said sample is contacted, in the presence of a polymerase and an endonuclease, with a sequence conversion oligonucleotide and a signal amplifier oligonucleotide. The disclosure also provides compositions and kits comprising such sequence conversion and signal amplifier oligonucleotides.
