A nucleic acid formulation for use in gene delivery comprising a nucleic acid and an anionic polymer is disclosed. Examples of the anionic polymer includes anionic amino acid polymer or poly-amino acid (such as poly-L-glutamic acid, poly-D-glutamic acid, poly-L-aspartic acid, poly-D-aspartic acid), poly-acrylic acid, polynucleotides, poly galacturonic acid, and poly vinyl sulfate.

Compositions and methods are provided for gene delivery to the respiratory tract. In particular, compositions comprising a nebulized nucleic acid/stabilizing agent complex, and methods employing such complexes for pulmonary gene delivery, are provided. Such complexes are preferably sonic nebulized.

Compositions of chitosan-based compounds and nucleic acid or oligonucleotide which are capable of delivery to a cell. Methods of preparation of the compositions. Methods of administering the compositions in vitro to cells in culture or in vivo to an organism.

Chitosan related compositions and methods for delivery of nucleic acids and oligonucleotides into a cell

Compositions and methods for administering nucleic acid compositions in vitro to cells in culture or in vivo to an organism whereby the uptake of nucleic acids is enhanced are provided. Various compositions, including thermo-reversible gels, are utilized to increase the viscosity of an administered nucleic acid formulation, thereby prolonging the localized bioavailability of the administered nucleic acid.

Formulated nucleic acid compositions and methods of administering the

Polynucleotide complexes are stabilized by adding a cryoprotectant compound and lyophilizing the resulting formulation. The lyophilized formulations are milled or sieved into a dry powder formulation which may be used to deliver the polynucleotide complex. Delivery of the polynucleotide to a desired cell tissue is accomplished by contacting the tissue with the powder to rehydrate it. In a preferred embodiment, a dry powder formulation is used to transfer genetic information to the cells of the respiratory tract.
