Precise Genome Editing of Drosophila with CRISPR RNA-Guided Cas9

Methods Mol Biol. 2015:1311:335-48. doi: 10.1007/978-1-4939-2687-9_22.


The readily programmable CRISPR-Cas9 system is transforming genome engineering. We and others have adapted the S. pyogenes CRISPR-Cas9 system to precisely engineer the Drosophila genome and demonstrated that these modifications are efficiently transmitted through the germline. Here we provide a detailed protocol for engineering small indels, defined deletions, and targeted insertion of exogenous DNA sequences within one month using a rapid DNA injection-based approach.
