CAMBRIDGE, Mass., Dec. 3, 2012 /PRNewswire/ --Scientists find that games and graphics help break down complex topics like plasmid cloning. (Photo: http://photos.prnewswire.com/prnh/20121203/PH22695 ) Plasmid Land is a simplistic game created to explain the importance of plasmid cloning in science. It shows that using a plasmid repository can save an incredible amount of time in biological research. Additionally, it shows the steps of molecular cloning including gene extraction and...

Studying self-replicating genetic units, called plasmids, found in one of the world's widest-ranging pathogenic soil bacteria -- the crown-gall-disease-causing microorganism Agrobacterium tumefaciens -- Indiana University biologists are showing how freeloading, mutant derivatives of these plasmids benefit while the virulent, disease-causing plasmids do the heavy-lifting of initiating infection in plant hosts. The research confirms that the ability of bacteria to cause disease comes at a...

Scientists involved in DNA vaccine research are currently focused on two major issues: the creation of effective delivery systems and the development of more efficient biomanufacturing strategies, reports Genetic Engineering & Biotechnology News (GEN). Top investigators in the field recently discussed these and other topics at a conference in San Diego entitled "DNA Vaccines: Building on Clinical Progress and Exploring New Targets," which was sponsored by the International Society of DNA...

The number of multiresistant strains of bacteria in hospitals is increasing. Bacteria acquire resistance to antibiotics through mutations in their chromosomes and by incorporating new genes, either from the surrounding environment or from other bacteria. Now, a research team at the Portuguese CBA research (University of Lisbon) and the Instituto Gulbenkian de Ciência has shown that, surprisingly, when both mechanisms of resistance are playing out in the bacterium...

Under the microscope, the bacteria start dividing normally, two cells become four and then eight and so on. But then individual cells begin "popping," like circus balloons being struck by darts. This phenomenon, which surprised the Duke University bioengineers who captured it on video, turns out to be an example of a more generalized occurrence that must be considered by scientists creating living, synthetic circuits out of bacteria. Even when given the same orders, no two cells will behave...

Plasmids, which are DNA molecules capable of independent replication in cells, have played an important role in gene technology. Researchers from Uppsala University in Sweden have now demonstrated that plasmid-based methods, which had been limited to single-cell organisms such as bacteria and yeasts, can be extended to mosses, opening the door to applications of a number of powerful techniques in plant research. The findings have been published in the distinguished journal Proceedings of the...

Biodesign Institute at Arizona State University associate research scientist Melha Mellata, a member of professor Roy Curtiss' team, is leading a USDA funded project to develop a vaccine against a leading poultry disease called avian pathogenic E. coli (APEC). APEC is part of a large, diverse group of microbes called extra-intestinal pathogenic E. coli (ExPEC). They cause a number of complex brain, lung and urinary tract diseases in human, animals, and birds. There is also considerable...

Promega Corporation announces a new plasmid isolation system that simplifies and speeds the preparation of plasmid DNA. The Promega PureYield(TM) Plasmid Miniprep System allows researchers to purify plasmid DNA in less than 10 minutes from 600microl to 3 ml of culture with fewer steps. The smooth work flow is further enhanced with the lysis/neutralization indication dye that confirms samples are processed effectively. In addition to streamlining lab processes, PureYield provides plasmid...
