Since the first application of ASOs against HBV in 1990 [ 31 ], several studies have further demonstrated the potential of ASOs in gene therapy.
WebWild-type S. pyogenes Cas9 requires magnesium (Mg 2+) cofactors for the RNA-mediated DNA cleavage; however, Cas9 has been shown to exhibit varying levels of activity in the presence of other divalent metal ions. For instance, Cas9 in the presence of manganese (Mn 2+) has been shown to be capable of RNA-independent DNA cleavage. WebTo assess whether SpCas9 nucleases and BEs exhibit consistent PAM profiles, we adapted the HT-PAMDA assay to function in the absence of SpCas9-mediated DNA cleavage. The …
