Abstract
The preparation of DNA-tagged liposomes containing an encapsulated prosthetic group tracer, pyrroloquinoline quinone (PQQ), and their application to the development of a sandwich-type hybridization assay for the visual detection of single-stranded DNA are described. Capture DNA is conjugated to the...

Abstract
Mitochondrial respiratory chain (RC) disorders (RCDs) are a group of genetically and clinically heterogeneous diseases because of the fact that protein components of the RC are encoded by both mitochondrial and nuclear genomes and are essential in all cells. In addition, the biogenesis, structure, a...

Abstract
It has been proposed that regions of microhomology in the human genome could facilitate genomic rearrangements, copy number transitions, and rapid genomic change during tumor progression. To investigate this idea, this study examines the role of repetitive sequence elements, and corresponding synten...

Abstract
DNA clones containing highly repetitive DNA sequences were selected from partial libraries of Lathyrus sativus and L. sylvestris. Two satellite DNA sequence families were isolated from the genome of the former species. A first family was made up of repeats that varied in length from 54-56 bp, and sh...

Abstract
During the course of our research on new actinobacterial sources, a novel actinomycete strain YIM 67013(T) was isolated from rhizosphere soil of Tripterygium wilfordii Hook. f. collected from Yunnan province, south-west China. The strain formed well-differentiated aerial and substrate mycelia, grew...

Abstract
We screened 85 isolates of Bacillus thuringiensis (Berliner), making up 57 different subspecies, and two isolates of Bacillus sphaericus (Meyer and Neide) for activity against immature horn flies, Haematobia irritans (L.), and stable flies, Stomoxys calcitrans (L.). The majority of B. thuringiensis...

Abstract
We have recently described a Dilute-'N'-Go protocol that greatly simplifies preparation and sequencing of both strands of an amplicon generated using linear-after-the-exponential (LATE)-PCR, an advanced form of asymmetric PCR . The same protocol can also be used to sequence all limiting primer stran...

Abstract
A sensitive and selective ligase-based signal-on electrochemical sensing method for adenosine-5'-triphosphate (ATP) detection had been developed using molecular beacon (MB)-like DNA. In this method, the biotin-tagged MB-like DNA was self-assembled onto a gold electrode to form a stem-loop structure...

Abstract
We detected the hybridization of HPV PCR products during temperature change process by a self-designed adjustable metal-clamping piezoelectric sensor. The study mainly involves sensor adjustment, probe immobilization and ice bath sample addition (at different concentrations and different volumes). T...

Abstract
An ultrasensitive assay for electrical biosensing of syphilis DNA was proposed by using target-guided formation of polyaniline (PANI) based on an enzymatically catalyzed method. The sensitive biodetection relies on the DNA hybridization and biotin-streptavidin interaction. After coupling of biotinyl...

Abstract
We report on a rapid method for DNA hybridisation and isolation within a microfluidic device, where all reaction and washing steps are performed in continuous flow in an automated fashion within less than two minutes. Magnetic particles were used as a solid support and manipulated through laminar fl...

Abstract
Target recognizing ternary mixed monolayer is constructed by simple sequential adsorption of thiol caped single stranded DNA (HS-ssDNA), 6-mercapto-1-hexanol (MCH) and 3-mercaptopropionic acid (MPA) diluents (abbreviated as HS-ssDNA/MPA/MCH) and applied for detection of DNA hybridization sequence by...

Abstract
A signal amplification based on a combination of hybridization chain reaction (HCR) and enzyme-enhancement was applied in the study of a novel biosensor. The target sequence was added as catalyst which was simply transmitted but did not disappear as the DNA double strand grew on the surface of magne...

Abstract
We employed DNA-functionalized gold nanoparticles (AuNPs) as a model system and found that if the alcohol content is less than approximately 30%, more alcohol leads to a faster DNA hybridization, although with a decreased melting temperature. The generality of this observation was independently veri...

Abstract
A method for the electrical contacting of redox enzymes that obtain oxidizing or reducing equivalents from small electron-transfer proteins is demonstrated. The electrochemical contacting of redox enzymes through their immobilization onto electrode supports offers great potential for technological a...

Abstract
The main objective of the present work was to develop a wheat genotype containing both the recessive crossability alleles (kr1kr1kr2kr2), allowing high crossability between 6x wheat and diploid rye, and the 1BL.1RS wheat/rye translocation chromosome. This wheat genotype could be used as a recipient...

A new label-free, optical method was developed to detect sequence-specific DNA based on supramolecular self-assembly. A cationic phenylene ethynylene oligomer with two pairs of positively charged side chains (OPE-2) can form a J-dimer or J-aggregate with negatively charged DNA by a combination of el...
