Development and application of DNA molecular probes

open access: yesAIMS Bioengineering, 2017
The development of DNA probes started from 1950's for diagnostic purposes and it is still growing. DNA probes are applied in several fields such as food, medical, veterinary, environment and security, with the aim of prevention, diagnosis and treatment ...

Furan-PNA : a mildly inducible irreversible interstrand crosslinking system targeting single and double stranded DNA [PDF]

open access: yes, 2016
We here report on the design and synthesis of tailor-made furan-modified peptide nucleic acid (PNA) probes for covalent targeting of single stranded DNA through a crosslinking strategy.

Fluorescent DNA hybridization probe preparation using amine modification and reactive dye coupling

open access: yesBioTechniques, 2004
Fluorescent nucleic acid hybridization probes traditionally have been generated by enzymatic incorporation of dye-labeled nucleotides, even though incorporation efficiency is low and variable from dye to dye.

Influence of the environment and probes on rapid DNA sequencing via transverse electronic transport [PDF]

open access: yes, 2007
We study theoretically the feasibility of using transverse electronic transport within a nanopore for rapid DNA sequencing. Specifically, we examine the effects of the environment and detection probes on the distinguishability of the DNA bases.

Method for detection of specific RNAs in agarose gels by transfer to diazobenzyloxymethyl-paper and hybridization with DNA probes.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1977
We describe a technique for transferring electrophoretically separated bands of RNA from an agarose gel to paper strips. The RNA is coupled covalently to diazobenzyloxymethyl groups on the paper.

A Technical Note on Quantum Dots for Multi-Color Fluorescence in situ Hybridization [PDF]

open access: yes, 2009
Quantum dots (Qdots) are semiconductor nanocrystals, which are photo-stable, show bright fluorescence with narrow, symmetric emission spectra and are available in multiple resolvable colors.

DNA probe for Aeromonas salmonicida [PDF]

open access: yesApplied and Environmental Microbiology, 1992
A DNA fragment that is specific to Aeromonas salmonicida has been isolated from a genomic DNA library by differential hybridization. The specificity of this fragment as a DNA probe for A. salmonicida was shown by hybridization against reference strains and clinical isolates of A. salmonicida, related aeromonads, and species from several other bacterial

Single-Labeled Oligonucleotides Showing Fluorescence Changes upon Hybridization with Target Nucleic Acids

open access: yesMolecules, 2018
Sequence-specific detection of nucleic acids has been intensively studied in the field of molecular diagnostics. In particular, the detection and analysis of single-nucleotide polymorphisms (SNPs) is crucial for the identification of disease-causing ...

DNA Stable-Isotope Probing (DNA-SIP) [PDF]

open access: yesJournal of Visualized Experiments, 2010
DNA stable-isotope probing (DNA-SIP) is a powerful technique for identifying active microorganisms that assimilate particular carbon substrates and nutrients into cellular biomass. As such, this cultivation-independent technique has been an important methodology for assigning metabolic function to the diverse communities inhabiting a wide range of ...
