CHOPCHOP

CHOPCHOP

CHOPCHOP is a web-based tool to select target sites for CRISPR/Cas9- or TALEN-directed mutagenesis. The CHOPCHOP algorithm predicts off-target binding of single-guide RNAs (sgRNAs) and TALENs using effective sequence alignment methods and visualizes the candidate target sites, restriction sites, primer candidates, together with color-coded quality scores.
