CRISPR-ERA

Here we describe a web tool called CRISPR-ERA for automated genome wide sgRNA design. CRISPR-ERA can provide different sgRNA searching approaches for genome editing, such as Cas9 nuclease. In addition, CRISPR-ERA also generate sgRNAs for gene activation or repression using our large-scale database of CRISPRi in different genomes. Now nine (two bacterial speices: E.coli, B. subtilis; one yeast: S. cerevasiae; C. elegans, fruit fly, zebrafish, mouse, rat, human) model organisms are provided in this web tool.
