Gupta, A., Christensen, R.G., Rayla, A.L., Lakshmanan, A., Stormo, G.D., and Wolfe, S.A. (2012) An optimized two-finger archive for ZFN-mediated gene targeting. Nature Methods. 9(6):588-590.
The widespread use of zinc-finger nucleases (ZFNs) for genome engineering is hampered by the fact that only a subset of sequences can be efficiently recognized using published finger archives. We describe a set of validated two-finger modules that complement existing finger archives and expand the range of ZFN-accessible sequences threefold. Using this archive, we introduced lesions at 9 of 11 target sites in the zebrafish genome.
