  • Patent number: 7664545
    Abstract: The present invention relates to a modular electrode system, and its use, for facilitating the introduction of a macromolecule into cells of a selected tissue in a body or plant. The modular electrode system comprises a non-symmetrically arranged plurality of needle electrodes; a hypodermic needle; an electrical connector that provides a conductive link from a programmable constant-current pulse controller to the plurality of needle electrodes; and a power source. In a preferred embodiment of the present invention, an operator can grasp the plurality of needle electrodes that are mounted on a support structure and firmly insert the them into the selected tissue in a body or plant. The macromolecules are then delivered via the hypodermic needle into the selected tissue. The programmable constant-current pulse controller is activated and constant-current electrical pulse is applied to the plurality of needle electrodes.

  • Publication number: 20080194511
    Abstract: One aspect of the current invention is an optimized synthetic mammalian expression plasmid (e.g. pAV0201). This new plasmid comprise a therapeutic element, and a replication element. The therapeutic element of the new plasmid comprises a eukaryotic promoter; a 5? untranslated region (“UTR”); a codon-optimized-eukaryotic therapeutic gene sequence; and a poly adenylation signal. The therapeutic elements of this plasmid are operatively linked and located in a first operatively-linked arrangement. Additionally, the optimized synthetic mammalian expression plasmid comprises replication elements, wherein the replication elements are operatively linked and located in a second operatively-linked arrangement. The replication elements comprise a selectable marker gene promoter, a ribosomal binding site, and an origin of replication. The first-operatively-linked arrangement and the second-operatively-linked arrangement comprise a circular structure of the codon optimized synthetic mammalian expression plasmid.

  • Publication number: 20040014645
    Abstract: Plasmid DNA delivered by injection/electroporation to the skeletal muscle can be expressed, and physiologic levels of transgene could be achieved into the circulation. Nevertheless, stabilization of naked DNA may be required and necessary in some cases, as prolonged storage at different temperatures before usage, injection into a large number of animals, etc. It is imperative that the associated compound should not be toxic to the cells (e.g. muscle cells) or cause breakage of plasmid DNA. It would be preferable for the coated DNA to have a similar or increased uptake into the target cells. Low molecular weight poly-L-glutamate compounds have all the desired properties. It was determined that mole/mole ratio DNA/PLG is the optimum concentration for gene therapeutic applications to the skeletal muscle, resulting in increased expression of the transgene, with no damage to the target tissue. Furthermore, stabilization of plasmid DNA by PLG has never been observed or described in the literature.

  • Publication number: 20030074679
    Abstract: Growth is improved by utilizing growth enhancement potential methodology to administer a nucleic acid sequence, such as GHRH or an analog, to a female animal, preferably through a parenteral route of administration. Piglets born from sows injected with DNA encoding GHRH are larger, and effects are demonstrated in subsequent pregnancies without additional administration(s) of the vector.
