Sequence specific detection of DNA using nicking endonuclease signal amplification (NESA)

We have developed a new method for identifying specific single- or double-stranded DNA sequences called nicking endonuclease signal amplification (NESA). A probe and target DNA anneal to create a restriction site that is recognized by a strand-specific endonuclease that cleaves the probe into two pieces leaving the target DNA intact. The target DNA can then act as a template for fresh probe and...

Nicking endonuclease and target recycles signal amplification assisted quantum dots for fluorescence detection of DNA.

An ultrasensitive fluorescence detection method for DNA based on nicking endonuclease (NEase) and target recycles assisted with CdTe quantum dots (QDs) is reported. In the detection system, when the target DNA is present, it hybridizes with a linker strand to from a duplex, in which the NEase recognizes specific nucleotide sequences and cleaves the linker strand. After nicking, the fragments of...

Ultrasensitive and selective DNA detection based on nicking endonuclease assisted signal amplification and its application in cancer cell detection.

By significantly circumventing the typical problem of high background induced by excess hemin itself, an ultrasensitive DNA amplified detection method is developed based on nicking endonuclease (NEase) assisted strand scission cycle, which is further successfully applied in cancer cell detection.

Ultrasensitive colorimetric DNA detection using a combination of rolling circle amplification and nicking endonuclease-assisted nanoparticle amplification (NEANA).

A combination of rolling circle amplification and nicking endonuclease-assisted nanoparticle amplification (NEANA) is used for the rapid, colorimetric detection of DNA. The integration of rolling circle amplification into the NEANA approach allows for detection of oligonucleotides with arbitrary sequences at ultralow concentrations.

Assistant DNA recycling with nicking endonuclease and molecular beacon for signal amplification using a target-complementary arched structure.

A simple and universal method for ultrasensitive "signal on" detection of DNA was developed with a target-complementary arched structure to release assistant DNA, which was recycled with nicking endonuclease to amplify the detectable fluorescent signal of molecular beacons.
