Dual sgRNAs facilitate CRISPR/Cas9‐mediated mouse genome targeting

The bacterial clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) system is a versatile RNA-guided mammalian genome modification system. One-step generation of mouse genome targeting has been achieved by co-microinjection of one-cell stage embryos with Cas9 mRNA and small/single guide (sg)RNA. Many studies have focused on enhancing the efficiency of this system. In the present study, we report that...
