產(chǎn)品簡(jiǎn)介

      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  9 basepair Mo saic End (ME) Tn5 transposase recognition sequences.
     In 1998 Goryshin and Reznikoff1demonstrated that a fully functional Tn5 transposition system could be reconstituted in vitro. 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.
     轉座子是在原核生物和真核生物的基因組中發(fā)現的可移動(dòng)DNA序列。 長(cháng)期以來(lái)，轉座子標記一直被認為是一種強大的研究工具，可用于隨機分布引物結合位點(diǎn)，創(chuàng )建基因“敲除”并將物理標簽或遺傳標簽引入大靶DNA。 一種常用的轉座系統是從革蘭氏陰性細菌中分離的Tn5系統。 盡管是自然發(fā)生的換位系統，但由于以下原因，Tn5系統可以很容易地用于研究實(shí)驗室的常規使用：
1）Tn5轉座酶是一種小的單亞基酶，已被克隆并純化成高比活性。
2）Tn5轉座酶無(wú)需宿主細胞因子即可進(jìn)行轉座。
3）Tn5轉座子插入目標DNA的隨機性很高。
4）Tn5轉座通過(guò)簡(jiǎn)單的“剪切和粘貼”過(guò)程進(jìn)行。 盡管化學(xué)性質(zhì)獨特，但結果類(lèi)似于使用限制性核酸內切酶，具有隨機序列特異性，并伴有DNA連接酶活性。
5）Tn5轉座酶將轉置其短9個(gè)堿基對的Mo saic End（ME）Tn5轉座酶識別序列之間的任何DNA序列。
     1998年，Goryshin和Reznikoff1證明可以在體外重建功能齊全的Tn5轉座系統。 此外，通過(guò)在轉座酶基因和19 bp Tn5 ME轉座酶識別序列中引入突變，與野生型Tn5相比，該系統的轉座效率已提高了1,000倍以上。
     Lucigen的EZ-Tn5轉座子工具（試劑盒和試劑）基于Goryshin和Reznikoff開(kāi)發(fā)的高活性Tn5轉座系統。
