工程化的锌指核酸酶(ZFN)形成了用于真核基因组的靶向、有效修饰的广泛适用的方法的基础。在最近的工作中,我们描述了OPEN(寡聚池工程),这是一种“开源”的基于组合选择的方法,用于设计功能良好的锌指阵列。我们还在直接比较中表明,OPEN方法具有比先前描述的用于工程化ZFN的“模块化组装”方法更高的成功率。在E中执行OPEN选择。大肠杆菌使用细菌双杂交系统,不需要专门的设备。在这里,我们提供了一个详细的协议,用于执行开放工程锌指阵列,具有很高的概率作为ZFN。使用OPEN,研究人员可以在大约8周内生成多个定制的ZFN。
Engineered zinc finger nucleases (ZFNs) form the basis of a broadly applicable method for targeted, efficient modification of eukaryotic genomes. In recent work, we described OPEN (Oligomerized Pool ENgineering), an “open-source,” combinatorial selection-based method for engineering zinc finger arrays that function well as ZFNs. We have also shown in direct comparisons that the OPEN method has a higher success rate than previously described “modular assembly” methods for engineering ZFNs. OPEN selections are performed in E. coli using a bacterial two-hybrid system and do not require specialized equipment. Here we provide a detailed protocol for performing OPEN to engineer zinc finger arrays that have a high probability of functioning as ZFNs. Using OPEN, researchers can generate multiple customized ZFNs in approximately 8 weeks.
