WTSI Genome Editing (WGE) is a website that provides tools to aid with genome editing of human and mouse genomes


CRISPR Finder

The CRISPR Finder will show CRISPR sites (paired or single) in and around genes. You can ask the finder to score the pairs for potential off-target sites, and browse individual and paired CRISPR sites using the Genoverse genome browser tool.

Example in genome browser:
Example in table:


Gibson Designer

The Gibson Designer will find the oligos in either Human or Mouse genomes that can be used to create targeting vectors by Gibson assembly. The Gibson Designer matches the vector design with CRISPR sites appropriate for the creation of exon deletions.
