Gateway® Technology

Gateway®克隆技术的基础是 λ噬菌体的位点特异性重组反应,一种保存遗传信息的有效的生化途径(见图1)。与传统的需要DNA限制性内切酶、DNA连接酶、凝胶电泳和DNA片段纯化等多个步骤的繁琐亚克隆方法相比,该方法只需一步生化反应而且操作方便、快捷(室温60分钟),省时高效(见图2)。另外,根据目的蛋白的生产和纯化的不同要求, Invitrogen公司提供一系列含有不同启动子和融合标签、以及在几种宿主表达的目标载体。有关Gateway®克隆技术的详细信息,请访问Invitrogen公司的网址:www.invitrogen.com。   图1. λ噬菌体的位点特异性重组反应。(点击放大) 图2.......

构建目的表达克隆的高效方法

ORFEXPRESS™-Shuttle Clone与目的载体attL和attR位点的重组反应可以生成目的表达克隆。这种特异性极高的重组反应不会导致LXR位点间碱基的增加或删除。 在 ORFEXPRESS™-Shuttle Clone中,起始密码子ATG上游的attL1和终止密码子下游的attL2位点之间是目的基因编码区。目的载体上带有 attR1和attR2重组位点I。  ORFEXPRESS™-Shuttle Clone和目的载体上attL1 x attR1和attL2 x attR2的重组反应由IHF、 Int和 Xis三种酶的混合物催化,生成带有ORF目的表达克隆。 To select suitable Expression Vector(s) for different hosts, 选择合适载体的表达克隆请浏览Inv......

Gateway克隆技术原理

Gateway克隆技术基于已研究的非常清楚的λ噬菌体位点特异重组系统,使用Int (integrase)和 IHF (Integration Host Factor) 催化重组反应, attB和attP位点的重组反应会生成attL和attR位点。 重组反应需要三种蛋白 (IHF、Int和 Xis)的参与。λ噬菌体attP位点和大肠杆菌基因组的attB位点可以发生定点重组,λ噬菌体DNA整合到大肠杆菌的基因组DNA中,两侧产生两个新位点:attL和attR。 上图离体的生物化学过程都基于 Gateway®克隆技术。
