Welcome to CRISPR fly design!

Our latest paper is out: gRNA multiplexing | tissue-specific CRISPR | Cpf1 genome editing. Read it here.

FlycartoonCRISPR/Cas is an exciting new technology for genome engineering. We have generated a set of tools that allows targeted mutagenesis in Drosophila melanogaster with high efficiency. The system consists of transgenic cas9 fly lines and gRNA expression vectors. Plasmids encoding target specific gRNAs can be injected into cas9 embryos or integrated into the genome and crossed to cas9 strains. By choosing appropriate tools it is possible to generate loss-of-function mutations in essential or non-essential genes in a germline restricted, ubiquitous or tissue-specific fashion. It is also possible to introduce designer mutations by homology directed repair, ranging from single nucleotide changes to GFP knock-ins. The papers describing our CRISPR/Cas tools are available here, here and here.

At CRISPRflydesign we believe in collaboration, sharing and open access. We started sending our transgenic cas9 lines to interested labs in July 2013, shortly after generating them. The website was launched in August 2013 to facilitate distribution of materials and to share experiences with their use. It allowed us to communicate some of our key results many months before formal publication. For the same reason we have also posted preprints of all our papers on the Biorxiv preprint server. This allowed access to our results months before the final paper was published. You can find a list of our publications along with an open access link below.
