  • Intravascular delivery of nucleic acid
    Patent number: 7507722
    Abstract: Disclosed is a process for transfecting genetic material into a mammalian cell to alter endogenous properties of the cell. The process comprises designing a polynucleotide for transfection. Then the polynucleotide is inserted into a mammalian blood vessel. Prior to insertion, subsequent to insertion, or concurrent with insertion the permeability of the vessel is increased using an exterior cuff thereby the genetic material is delivered to the parenchymal cell.

  • Formation of polyampholytes in the presence of a polyion
    Patent number: 7470539
    Abstract: Polyampholyte are able to condense nucleic acid to form small complexes which can be utilized in the delivery of nucleic acid to mammalian cells. The polyampholytes can be formed prior to interaction with nucleic acid or they can be formed in the presence of nucleic acid. Stabilized polycation/nucleic acid complexes can be modified to reduce the positive charge of the polycation and add targeting ligands without destabilizing the complex. The resultant particles retain their small size and are more effective in delivery of nucleic acid to cells in vivo.
