CRISPR/Cas9 Guide RNA Design Rules for Predicting Activity

A critical stage in performing gene editing experiments using the CRISPR/Cas9 system is the design of guide RNA (gRNA). In this chapter, we conduct a review of the current gRNA design rules for maximizing on-target Cas9 activity while minimizing off-target activity. In addition, we present some of the currently available computational tools for gRNA activity prediction and assay design.
