Product information

EZ-Tn5™ Transposase is a hyperactive form of Tn5 transposase. 1 The highly purified, single-subunit enzyme can be used to randomly insert (transpose or "hop") any EZ-Tn5 Transposon into any target DNA in vitro with an efficiency up to >10 6 insertion clones per standard reaction. When incubated with an EZ-Tn5 Transposon in the absence of Mg 2+, a stable EZ-Tn5 Transposome™ complex is formed. The Transposome is so stable that it can be electroporated into living cells. Once in the cell, the Transposome is activated by intracellular Mg 2+ and the EZ-Tn5 Transposon component is randomly inserted into the host's genomic DNA. The three-dimensional structure of a Transposome complex has been elucidated. 2

Applications

  • In vitro insertion of an EZ-Tn5 Transposon into DNA cloned in vectors, such as plasmids, fosmids, cosmids, or BACs as well as in vitro insertion into linear DNA.*
  • Preparation of EZ-Tn5 Transposomes for in vivo transposition following electroporation into living cells.**

A typical EZ-Tn5 transposition reaction requires four components: (1) the EZ-Tn5 Transposase; (2) an EZ-Tn5 Transposon; (3) a target DNA; and (4) the presence of Mg 2+. The highly random insertion of an EZ-Tn5 Transposon into the target DNA 3 proceeds by a cut-and-paste mechanism, 1 catalysed by the EZ-Tn5 Transposase, and results in a 9-bp duplication of target DNA sequence immediately adjacent to both ends of the Transposon.

Benefits

  • Specifically and uniquely recognises the Outer End sequences of naturally occurring Tn5 and mini-Tn5 transposons and the hyperactive Mosaic Ends of EZ-Tn5 Transposons.
