ICTS Pilot Grant Recipients Forge New Ground to Identify Disease ...

DNA is a duplex, therefore the patient's DNA, labeled with a dye, will hybridize to DNA on the array. The investigators then treat the array with an enzyme called a mismatch endonuclease that will seek out and digest any places in the DNA duplexes that contain mismatches, thus identifying the mutation's location.  “You take someone’s genomic DNA, chop it up, label it using a florescent dye, and hybridize it to the microarray so that complementary features on the array can bind with the labeled DNA,” explained Manak. “Treatment with the enzyme results in cleavage at the mismatches, [more...]

A robust universal method for extraction of genomic DNA from ...

The intactness of DNA is the keystone of genome-based clinical investigations, where rapid molecular detection of life-threatening bacteria is largely dependent on the isolation of high-quality DNA. Various protocols have been so far developed for genomic DNA isolation from bacteria, most of which have been claimed to be reproducible with relatively good yields of high-quality DNA. Nonetheless, they are not fully applicable to various types of bacteria, their processing cost is relatively high, and some toxic reagents are used. The routine protocols for DNA extraction appear to be [more...]

DNA strides into organic synthesis

The walker and three 'stations', made from specific DNA sequences, organise themselves along the track using the normal pairing of DNA bases. 'The walker will move unidirectionally along the track,' Liu says. 'We attached chemical reactants to the walker and each station on the track. As the DNA walker moves from station to station, a programmed series of chemical reactions takes place.' The walking strand of DNA moves to each station (blue, red and green) in turn and reacts with the attached reagent © Nature Nanotechnol. In this way, the Harvard team was able to perform three acylation [more...]

There was some exciting news yesterday from the next-generation sequencing (NGS) field, with the buy-out of Ion Torrent - a start-up that’s developed a novel DNA sequencing machine – by the life-sciences behemoth Life Technologies (for a whopping 350million dollars). The technology for sequencing of DNA – the blueprint of all life – is at an exciting stage. Ten years ago, the complete human genome was sequenced at the cost of several billion dollars and decades of attempt. Today, a full genome can be sequenced for as little as $10,000 and in less than a week. The price and time are [more...]

Technology Review: A Portable DNA Detector

A new portable DNA analyzer performs real-time analysis of blood samples left at the scene of a crime. Researchers at the University of California, Berkeley, developed the device, which packs microfluidics, electronics, optics, and chemical detection technology into a single briefcase-sized unit. "While previous groups have developed lab-on-a-chip systems, none of them have succeeded in making a completely portable, robust system that can be used at a scene," says team leader Richard Mathies.

Finally, a second size-exclusion chromatography step was carried out to purify the plasmid DNA from other small molecular-weight contaminants. Analytical methods proved that the purified plasmid DNA had a purity of 95% after Sephacryl S1000. Plasmid identity was confirmed by restriction enzyme digestion. Biological activity of the purified plasmid was confirmed in vivo; immunized mice developed a positive antibody response against all HCV structural antigens.

Links Between XMRV and Human Disease Studied | Health News

A previous study in the United States found evidence of XMRV DNA in 67 percent of subjects with chronic fatigue syndrome (CFS), compared to 3.7 percent of healthy controls. Subsequent studies in Europe, however, were unable to demonstrate the presence of XMRV in CFS subjects or healthy controls. “The findings suggest that in the population we tested, XMRV is not associated with chronic fatigue syndrome and suggests that differences in PCR technique from study to study do not explain the disparate results seen in XMRV studies of chronic fatigue syndrome,” Dr. Tsibris said. A second study, [more...]

With some other in vitro tests, like DNA analysis, cells need to be killed in order to be studied. In this analysis method, a change in fluorescence occurs when caspase-3, an indicator of cell apoptosis, is activated. In Wu's test, increasing concentrations of etoposide demonstrated correspondingly higher activation of caspase-3. In a control-group chip without etoposide, caspase-3 was not activated.Wu also said that, "Unlike conventional methods, the microfluidic device permits quantitative data to be obtained from individual cells; the device requires fewer numbers of cells and allows [more...]
