Figure 7: SpdCas9-assisted gene editing by the type V Cpf1 from Francisella novicida (FnCpf1) in K562 cells.

(a) FnCpf1 and SpdCas9 targets in the human POR locus. Targets are indicated by bars and PAMs are highlighted in purple (SpdCas9) and dark blue (FnCpf1). (b) FnCpf1 target cleavage activities (% indels) with or without SpdCas9 binding at proximal locations. The Fn-crRNA and Sp-sgRNA numbers correspond to the target numbers in a. Data are representatives of three independent experiments. M, wide-range DNA markers; ND, not determined.
