A Label-free and Turn-on Fluorescence Strategy for DNA Detection with a Wide Detection Range Based on Exonuclease III-aided Target Recycling Amplification.
In the present work, a simple and sensitive turn-on fluorescence method for DNA detection was developed. It was explored based on the N-methyl mesoporphyrin IX (NMM)/G-quadruplex DNA system as a reporter and exonuclease III (Exo III)-aided target recycling amplification to ensure sensitivity. Our method showed an ultra-wide detection range from 10 fM to 100 nM with a low linear detection limit ...
متن کاملUltrasensitive fluorescence polarization DNA detection by target assisted exonuclease III-catalyzed signal amplification.
Single stranded DNA sequences can be detected by target assisted exonuclease III-catalyzed signal amplification fluorescence polarization (TAECA-FP). The method offers an impressive detection limit of 83 aM within one hour for DNA detection and exhibits high discrimination ability even against a single base mismatch.
متن کاملA Label-free and Highly Sensitive Fluorescence Strategy for Mercury Ion Detection Based on Exonuclease III-aided Recycling Amplification.
In this paper, we describe a simple and highly sensitive fluorescence strategy of mercury ions based on exonuclease III (Exo III)-aided target recycling amplification to ensure sensitivity. With an ultra high sensitivity (1 pM), our strategy has been simple and cost-effective, which does not need any artificial modification fluorescence groups, and can be carried out in a pot. It also shows exc...
متن کاملA sensitive fluorescence strategy for telomerase detection in cancer cells based on T7 exonuclease-assisted target recycling amplification.
A sensitive fluorescence strategy based on T7 exonuclease-assisted target recycling amplification was developed for telomerase detection in cancer cells. The novel strategy improved the fluorescence signal and sensitivity compared with the previously reported methods.
متن کاملAn electrochemical aptasensor based on hybridization chain reaction with enzyme-signal amplification for interferon-gamma detection.
A novel electrochemical aptasensor based on hybridization chain reaction (HCR) with enzyme-signal amplification was constructed for the detection of interferon-gamma (IFN-γ). In this aptasensor, the recognition probes which contained the sequence of IFN-γ aptamer were initially binded to IFN-γ, and the unbound recognition probes were captured on the electrode as an initiator to trigger the HCR....
