| Transposons are mobile DNA sequences found in the genomes of prokaryotes and eukaryotes. Transposon tagging has long been recognized as a powerful research tool for randomly distributing primer binding sites, creating gene“knockouts”, and introducing a physical tag or a genetic tag into large target DNAs. One frequently used transposition system is the Tn5 system isolated from gram-negative bacteria. Though a naturally occurring transposition system, the Tn5 system can be readily adapted for routine use in research laboratories for the following reasons: 1) Tn5 transposase is a small, single subunit enzyme that has been cloned and purified to high specific activity.2) Tn5 transposase carries out transposition without the need for host cell factors. 3) Tn5 transposon insertions into target DNA are highly random. 4) Tn5 transposition proceeds by a simple“cut and paste”process. Although the chemistry is unique, the result is similar to using a restriction endonuclease, with random sequence specifi city, accompanied by a DNA ligase activity. 5) Tn5 transposase will transpose any DNA sequence contained between its short 9basepair Mo saic End (ME) Tn5 transposase recognition sequences. In 1998 Goryshin and Reznikoff1demonstrated that a fully functional Tn5 transposition system could be reconstituted invitro. Additionally, the transposition efficiency of this system has been increased more than 1,000-fold compared to wild-type Tn5 by introducing mutations in the transposase gene and in the 19-bp Tn5 ME transposase recognition sequence. Lucigen’s EZ-Tn5 Transposon Tools (kits and reagents) are based on the hyperactive Tn5 transposition system developed by Goryshin and Reznikoff. |

技术参数 产品优点 - Insert a kanamycin, tetracycline, or DHFR selectable marker into any DNA sequence in vitro
- Skip primer walking - simplify Sanger sequencing of large DNA inserts
- Speed functional analysis without subcloning - create libraries of random mutants from purified DNA
- Minimize insertion bias with the hyperactive Tn5 system, known for highest level of randomness
产品应用 - Introduce the R6Kγori into any plasmid and/or cloning vector.
- Propagate vectors from non-E. coli species in E. coli. Randomly insert the EZ-Tn5 <R6Kγori/KAN-2> Transposon into any foreign vector, transform an E. coli pir+ or E. coli pir-116 strain and select on kanamycin plates.
- Propagate genomic DNA fragments from any species as independently replicating plasmids in E. coli . Randomly insert the EZ-Tn5 <R6Kγori/KAN-2> Transposon in vitro into self-ligated genomic DNA fragments, transform an E. coli pir+ strain and select on kanamycin plates
