Playback Cloning: Simple, Reversible, Cost-effective Cloning for the Combinatorial Assembly of Complex Expression Constructs

Abstract

With advancements in multicomponent molecular biological tools, the need for versatile, rapid and cost-effective cloning that enables successful combinatorial assembly of DNA plasmids of interest is becoming increasingly important. Unfortunately, current cloning platforms fall short regarding affordability, ease of combinatorial assembly and, above all, the ability to iteratively remove individual cassettes at will. Herein we construct, implement and make available a broad set of cloning vectors, called PlayBack vectors, that allow for the expression of several different constructs simultaneously under separate promoters. Overall, this system is substantially cheaper than other multicomponent cloning systems, has usability for a wide breadth of experimental paradigms and includes the novel feature of being able to selectively remove components of interest at will at any stage of the cloning platform.
