 This tool provides access to a pre-computed database of short guide RNAs (gRNAs) for CRISPR approaches in *Drosophila*. The gRNAs are appropriate for CRISPR applications using *S. pyogenes* Cas9 (PAM sequence of NGG or NAG). You can view and filter gRNAs in the context of a GBrowse genome browser.

##  Additional Resources 

 You might also be interested in our [CRISPR gRNA efficiency predictor tool](/crispr-efficiency), which can be used with gRNAs designed using our own or other CRISPR design algorithms. We recommend visiting the [FlyBase resources wiki](http://flybase.org/wiki/FlyBase:All_Resources), the [CRISPR fly design website](http://www.crisprflydesign.org/) (F. Port), and the [flyCRISPR website](http://flycrispr.molbio.wisc.edu/), for general information on CRISPR applications in *Drosophila*.
