CRISPRon(v1.0): CRISPR-Cas9 guide efficiency prediction


The CRISPRon webserver is dedicated to design of gRNAs for CRISPR/Cas9-mediated genome editing experiments. The model implemented in the webserver predicts on-target cleavage efficiency of CRISPR/Cas9-gRNAs at target sites designed from a given genomic sequence. Using the webserver, you can find possible CRISPR/Cas9 targets and obtain the predicted Cas9/gRNA cleavage effiency (indel frequency obtained at approx. 3 days after gRNA delivery). Selected targets (whose sequence corresponds to that of the gRNA+PAM) can be then transferred to our CRISPRoff webserver, which reports potential off-targets and the genome-wide specificity of gRNAs (see the CRISPRoff i page for details).

Details on how to use the webserver and descriptions of the input and outputs are given on the Help page.
