Also, it is unclear if the biochemically identified minimal crRNA scaffold is the optimal crRNA scaffold for Cpf1-mediated gene editing in eukaryotic systems17,25,28, and whether extending the 5′ end could enhance editing efficiency.
The ZFs may enhance editing efficiency by optimizing editosome organization, RNA interaction, and dynamic movements.
A first experiment was to assess whether the foot-based method enhanced editing performance compared to conventional mouse use and to identify which type of foot control is most convenient for users.
The core JV2 functionality present in JVL and JVD provides significantly enhanced editing and viewing capabilities when compared to JV1.
Despite such exciting achievements we have witnessed, enormous challenges still remain for further advances of genome-editing techniques, in particular, to enhance the editing efficiency and to eliminate the off-target events.
This transient cold shock was previously reported to enhance genome editing in mammalian cells57.
We performed additional experiments to determine if the exogenously added DNA had to have homology to the Cpf1 RNP target site in order to enhance gene editing.

This review highlights the attributes and advantages of chemically synthesized guide RNAs including the incorporation of chemical modifications to enhance gene editing efficiencies in certain applications.
The sgRNA of SpCas9 has undergone extensive sequence, length, and chemical optimizations to enhance gene editing activity10,13,16,32,33,34. In contrast Cpf1 crRNA engineering remains to be intensively explored, although a few studies have demonstrated that modifications at the 3′ end can improve Cpf1 activity18,31.
Aided by TALENs to enhance genome editing, we generated human ESCs with homozygous mutation on GATA2 (GATA2 −/− hESCs).
