The empty CRISPR-Cas9–i53 cloning vector is digested with the type IIS restriction enzyme BbsI (isoschizomer: BpiI). The backbone fragment is used for subsequent ligation with a spacer fragment derived from the dimerization of two deoxyoligonucleotides. The ligation product is then used for transformation of competent E.coli.
