WebJan 1, 2014 · Endonuclease cleavage assays can be used to characterize the activity of purified Cas9 or test the in vitro efficacy of a particular guide RNA or a target DNA site. In these assays, the target DNA site, including its PAM motif, is either inserted into a plasmid or provided in the form of an oligonucleotide duplex. WebAug 10, 2016 · In this study, we designed a convenient and sensitive in vitro test method, which was based on electrochemiluminescence (ECL) technology for evaluating cleavage activity of the CRISPR/Cas9 system. It was find that Cas9 can tolerate some common genetic modifications to its target DNA.
