A portable and label-free pH-mediated electrochemical method for the detection of DNA amplification is described. With protons released as readouts, DNA amplifications were detected in real-time or at the end-point.
A developmental validation study based on recommendations of the Scientific Working Group on DNA Analysis Methods (SWGDAM) was conducted on a multiplex system of 10 Cannabis sativa short tandem repeat loci. Amplification of the loci in four multiplex reactions was tested across DNA from dried root, stem, and leaf sources, and DNA from fresh, frozen, and dried leaf tissue with a template DNA ran...
Forensic biological evidence often contains low quantities of DNA or substantially degraded DNA which makes samples refractory to genotype analysis. One approach that shows promise to overcome the limited quantity of DNA is whole genome amplification (WGA). One WGA technique, termed rolling circle amplification (RCA), involves the amplification of circular DNA fragments and this study evaluates...
To evaluate the influence of diet on faecal DNA amplification, 11 captive brown bears (Ursus arctos) were placed on six restricted diets: grass (Trifolium spp., Haplopappus hirtus and Poa pratensis), alfalfa (Lupinus spp.), carrots (Daucus spp.), white-tailed deer (Odocoileus virginianus), blueberries (Vaccinium spp.) and salmon (Salmo spp.). DNA was extracted from 50 faecal samples of each res...
Polymerase Chain Reaction (PCR) is a major DNA amplification technology from molecular biology. The quantitative analysis of PCR aims at determining the initial amount of the DNA molecules from the observation of typically several PCR amplifications curves. The mainstream observation scheme of the DNA amplification during PCR involves fluorescence intensity measurements. Under the classical ass...

Tomato yellow leaf curl virus (TYLCV) is a major tomato virus in tropical and subtropical regions. In this study, 134 accessions of Solanum lycopersicum and six accessions of Solanum peruvianum were assessed for resistance to an Iranian isolate of TYLCV. Plants were inoculated using whiteflies (Bemisia tabaci) and the reaction of plants was evaluated based on either disease symptoms or viral DN...
We have efficiently amplified plasmid DNA from single yeast colonies using rolling circle amplification (RCA). The amplified DNA can be directly used for restriction digestion, DNA sequencing, or yeast transformation. The RCA-based high-fidelity amplification would be useful for plasmid manipulation in a variety of yeast-based systems, particularly for high-throughput analyses.
