A Rapid TALEN Assembly Protocol

Abstract Owing to their modular and highly specific DNA recognition mode, transcription activator-like effector nucleases (TALENs) have been rapidly adopted by the scientific community for the purpose of generating site-specific double-strand breaks (DSBs) on a DNA molecule. A pair of TALENs can be used to produce random insertions or deletions of various lengths via nonhomologous end-joining or together with a homologous donor DNA to induce precise sequence alterations by homologous recombination (HR). Here, we describe a method for TALEN assembly (easyT) and a strategy for genome engineering via HR.
