WebFeb 4, 2024 · SpCas9 nickase (Cas9n) (14) A single alanine substitution (D10A or H840A) transforms Cas9 into a “nickase” that can only cut one strand of target DNA. Two Cas9 nickases must be paired (one bearing D10A and the other H840A) in order to generate a double-strand break. This approach is associated with fewer off-target DSBs than SpCas9.
