Members of the team had previously reported that P. rustigianii carries a cytolethal distending toxin virulence gene on its plasmid. Elimination of this gene did not reduce the bacteria's ...

A scaleable method for the liquid-phase separation of plasmid DNA from RNA. In the course of experiments on the potential of nucleic acid compaction for enhancement of chromatographic adsorption ...
