Abstract: A general method and strains of bacteria are described, by means of which it is possible to dramatically purify plasmid DNA with respect to genomic DNA, and RNA. In one preferred embodiment, lysis and nuclease removal of host nucleic acids is an integral component of the fermentation/harvest process, and as such, achieves increased yield and purity with simplified downstream purification and reduced waste streams, thus reducing production costs.
Abstract: Improvements in plasmid DNA production technology are needed to insure the economic feasibility of future DNA vaccines and DNA therapeutics. General methods are described, by means of which it is possible to dramatically increase plasmid DNA productivity in a fermentor. These processes feature fed-batch fermentation strategies, combined with novel growth and induction phase temperature shifts.

Abstract: Improvements in plasmid DNA production technology are needed to insure the economic feasibility of future DNA vaccines and DNA therapeutics. General methods are described, by means of which it is possible to dramatically increase plasmid DNA productivity. These processes feature RNA based inducers of plasmid copy number.
Abstract: Fusion proteins including maltodextrin-binding protein (MBP) domains that are thermally stable and soluble are provided. Methods for forming and using the fusion proteins are also provided.
Abstract: Improved DNA vaccine plasmids are disclosed. The improved plasmids eliminate all extraneous sequences, and have superior eukaryotic expression, improved yield and stability during bacterial production, facilitate flexible targeting of antigens to various intracellular destinations, and novel RNA-based functionality. These vectors are utilized in novel immunization methods wherein combinations of immunostimulatory DNA vaccine plasmids that target antigens to various intracellular destinations are used to elicit improved immune response.

Abstract: The invention relates to a method for directing the self-assembly of a gene or gene assembly having three and preferably six or more fragments in a directionally and spatially ordered fashion to produce a gene, gene vector or large nucleic acid molecule. The method can be used to create libraries, such as combinatorial libraries. In another embodiment of the invention a vector is described for the incorporation and screeming of endogenous mouse promoter elements for the identification of cell-specific promoters.
