CHOPCHOP v2: a web tool for the next generation of CRISPR genome engineering.
We have released a new and improved version of CHOPCHOP! This version incorporates the latest large-scale datasets to give each sgRNA a more sophisticated efficiency score, and it includes a number of new options, including Cpf1, Cas9 nickase, alternative PAM motifs and a host of new organisms.
Congratulations to the first authors Tessa and Kornel Labun from ex-postdoc Eivind Valen's lab!
