Nanopore based sequence specific detection of duplex DNA for genomic profiling.
We demonstrate a purely electrical method for the single-molecule detection of specific DNA sequences, achieved by hybridizing double-stranded DNA (dsDNA) with peptide nucleic acid (PNA) probes and electrophoretically threading the DNA through sub-5 nm silicon nitride pores. Bis-PNAs were used as the tagging probes in order to achieve high affinity and sequence specificity. Sequence detection i...
متن کاملNanopore-based conformational analysis of a viral RNA drug target.
Nanopores are single-molecule sensors that show exceptional promise as a biomolecular analysis tool by enabling label-free detection of small amounts of sample. In this paper, we demonstrate that nanopores are capable of detecting the conformation of an antiviral RNA drug target. The hepatitis C virus uses an internal ribosome entry site (IRES) motif in order to initiate translation by docking ...
متن کاملNanoSim: nanopore sequence read simulator based on statistical characterization
Background The MinION sequencing instrument from Oxford Nanopore Technologies (ONT) produces long read lengths from single-molecule sequencing - valuable features for detailed genome characterization. To realize the potential of this platform, a number of groups are developing bioinformatics tools tuned for the unique characteristics of its data. We note that these development efforts would ben...
متن کاملNanopore-based detection of circulating microRNAs in lung cancer patients
MicroRNAs are short RNA molecules that regulate gene expression, and have been investigated as potential biomarkers because their expression levels are correlated with various diseases. However, detecting microRNAs in the bloodstream remains difficult because current methods are not sufficiently selective or sensitive. Here, we show that a nanopore sensor based on the α-haemolysin protein can s...
متن کاملNanopore Detection of 8-Oxoguanine in the Human Telomere Repeat Sequence
The human telomere repeat sequence 5'-TTAGGG-3' is a hot spot for oxidation at guanine, yielding 8-oxo-7,8-dihydroguanine (OG), a biomarker of oxidative stress. Telomere shortening resulting from oxidation will ultimately induce cellular senescence. In this study, α-hemolysin (α-HL) nanopore technology was applied to detect and quantify OG in the human telomeric DNA sequence. This repeat sequen...
