  • Publication number: 20150079636
    Abstract: Circular nucleic acid vectors that provide for persistently high levels of protein expression are provided. The circular vectors of the subject invention are characterized by being devoid of expression-silencing bacterial sequences, where in many embodiments the subject vectors include a unidirectional site-specific recombination product hybrid sequence in addition to an expression cassette. Also provided are methods of using the subject vectors for introduction of a nucleic acid, e.g., an expression cassette, into a target cell, as well as preparations for use in practicing such methods. The subject methods and compositions find use in a variety of different applications, including both research and therapeutic applications. Also provided is a highly efficient and readily scalable method for producing the vectors employed in the subject methods, as well as reagents and kits/systems for practicing the same.
