Metagenome Sequencing In contrast, metagenome sequencing transcends the limitations of individual 16S rRNA sequences by encompassing all genetic material within a sample, including host DNA and microbial genomes. This comprehensive approach allows researchers to gain insights into both the taxonomic composition and functional potential of microbial communities. By employing ...
Host Cell DNA Testing is a tool to accurately quantify the amount of host cell DNA residues in biologics using qpcr and other methods. ...
The process of 16S/18S/ITS amplicon sequencing entails DNA extraction from environmental samples, careful selection of universal primers to amplify the target region of 16S/18S/ITS, and the subsequent detection of sequence variations and abundance in the target region. This facilitates the study of differences in environmental microbial diversity ...
Metagenomics presents a powerful tool to study prokaryotes and viruses in the environment via the analysis of their DNA obtained directly from environmental samples. This technology considers the DNA of microbes in a population as a whole. ...
Background DNA-stable isotope probing technology (DNA-SIP) is a molecular ecology technology that uses stable isotopes to trace the genomic DNA of microorganisms in complex environments. ...
Metagenomics presents a powerful tool to study prokaryotes and viruses in the environment via the analysis of their DNA obtained directly from environmental samples. This technology considers the DNA of microbes in a population as a whole. ...
Perfect for use with: High density solutions Viscous solutions (like resins, fats, protein solutions and oils) Dense solutions Foaming liquids Volatile liquids Problematic liquids Ideal for use in: Food and beverage manufacture Cosmetic production Forensic Science Molecular Biology Environmental research DNA sample work and PCR Tips & ...
In a recent article, we described how environmental DNA (eDNA) has been used to detect the presence of aquatic species in lakes and rivers. ...
Studies have shown that soils disturbed by environmental change boast less bacterial diversity than undisturbed soils. ...

One method that is gaining widespread use, and relies on a simple filtration method, is the analysis of environmental DNA (eDNA) from local waterways. As animals inhabit a river, lake, or pond, they shed off skin cells and other body waste that often contains that animal’s own unique DNA. These shed cells and their DNA ...
While many studies report clinical OXA-48-like producers, few reports refer blaOXA-48-like genes in environmental bacteria. The main goal of this study was to evaluate the diversity of blaOXA-48-like genes in aquatic systems, using culture-independent approaches. For that, environmental DNA was obtained from riverine and estuarine water and used ...
Anammox bacteria are extremely slow growing and can be extremely sensitive to small environmental changes. Modern DNA methods are the only way to conclusively identify and quantify these bacteria in treatment systems to help optimize these efficient processes. ...
In a study published last January in PLoS ONE, researchers led by Ryan Kelly of the University of Washington identified most of the bony fishes in the aquarium’s great tank by deciphering the DNA in samples of the tank’s water. Environmental DNA sampling is the latest tool in biodiversity monitoring in marine and aquatic systems. ...

The Comet assay is playing an increasing role in studies to determine possible links between environmental pollutants and DNA integrity. The assay is an ideal biomarker for such investigations due to its sensitivity and reliability in detecting DNA damage and repair. ...
Attention was also paid to the relationship between internal biomarker dose and environmental pollution levels through a combined use of biomonitoring epidemiological study design and environmental monitoring. Marker levels of internal dose (in blood and urine), DNA damage and oxidative stress tend to be higher mostly in highly exposed workers, ...
The contamination effects on soil functional qualities and plant nutrition were evaluated; furthermore DNA damage with short-term genotoxicity tests and DNA biosensor on polluted soils and gravitational water, was detected. The genotoxic effects were evaluated on Vicia faba seedlings by two different short-term tests: comet assay and micronuclei test. A ...
Three different gels (Sepharose 4B, Sephadex G-200, and Sephadex G-50) were evaluated as a means of removing humic contaminants from DNA extracts of environmental samples. Sepharose 4B gave superior separation of DNA from humics, and DNA purified in this way showed consistently greater amplification than DNA ...
