Quantitative Analysis of Nucleic Acid Hybridization on Magnetic Particles and Quantum Dot-Based Probes

open access: yesSensors, 2009
In the present study we describe sandwich design hybridization probes consisting of magnetic particles (MP) and quantum dots (QD) with target DNA, and their application in the detection of avian influenza virus (H5N1) sequences. Hybridization of 25-, 40-,

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.

A strategy for the characterization of minute chromosome rearrangements using multiple color fluorescence in situ hybridization with chromosome-specific DNA libraries and YAC clones [PDF]

open access: yes, 1993
The identification of marker chromosomes in clinical and tumor cytogenetics by chromosome banding analysis can create problems. In this study, we present a strategy to define minute chromosomal rearrangements by multicolor fluorescence in situ ...

Multicolor chromosome bar codes [PDF]

open access: yes, 2006
Chromosome bar codes are multicolor banding patterns produced by fluorescence in situ hybridization (FISH) with differentially labeled and pooled sub-regional DNA probes.

DNA fingerprinting and cloning of hypervariable minisatellite repeats in salmonids [PDF]

open access: yes, 1994
We used heterologous jeffreys' 33.6 core sequence and microsatellites (CAC)(5) and (CA)(12) as probes and compared them with probes based on the minisatellite sequences from tilapia (Oreochromis niloticus) and Atlantic salmon (Salmo salar) in ...

Sequence-specific cleavage of double helical DNA by triple helix formation [PDF]

open access: yes, 1987
Homopyrimidine oligodeoxyribonucleotides with EDTA-Fe attached at a single position bind the corresponding homopyrimidine-homopurine tracts within large double-stranded DNA by triple helix formation and cleave at that site.

DNA tetrahedron for fluorescence anisotropy of intercalators

open access: yesHe jishu, 2021
BackgroundThe fluorescence anisotropy of intercalative dye plays important roles in nucleic acid analysis, the construction of fluorescent probes, and biosensing.

DNA amplified fingerprinting, a useful tool for determination of genetic origin and diversity analysis in Citrus [PDF]

open access: yes, 1995
We used three short repetitive nucleotide sequences [(GTG)5, (TAC)5, and (GACA)4] either as radiolabeled probes for hybridization with restricted Citrus DNA or as single primers in polymerase chain reaction amplification experiments with total genomic ...

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 ...
