Abstract

Methods are provided for introducing a biologically active agent into cells of a subject by injecting the agent with a needle-free injector and applying a pulsed electric field to the region of tissue to cause electrotransport of the agent into cells of the tissue. Preferably the agent is either ionized to some degree or contained in an ionized medium for electrotransport. The needle-free injector can serve as an electrode by which the pulsed electric field is applied to the region of tissue. The active agents delivered into cells by this method include small molecules, polynucleotides, polypeptides, and the like. Polynucleotides introduced into cells using this method can be used to accomplish gene therapy or to modulate expression of an endogenous gene.
