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.
