A process is described for the delivery of a therapeutic polynucleotide to a tissue suffering from or potentially suffering from ischemia. An ionic polymer is utilized in “recharging” (another layer having a different charge) a condensed polynucleotide complex for purposes of nucleic acid delivery to a cell. The resulting recharged complex can be formed with an appropriate amount of positive or negative charge such that the resulting complex has the desired net charge.
An polyampholyte is utilized in a condensed polynucleotide complex for purposes of nucleic acid delivery to a cell. The complex can be formed with an appropriate amount of positive and/or negative charge such that the resulting complex can be delivered to the extravascular space and may be further delivered to a cell.
A polyampholyte is utilized in a complex with siRNA for purposes of siRNA delivery to a cell. The complex can be formed with an appropriate amount of positive and/or negative charge such that the resulting complex can be delivered a cell in vivo or in vitro.
