[Methods of Evaluating the Efficiency of CRISPR/Cas Genome Editing]

The CRISPR/Cas system is currently widely used for genome editing. The procedure of genome editing includes two necessary steps: (i) searching for the most effective guide RNA, and (ii) analyzing clones for presence of the desired mutation. This review presents the methods used to assess the efficiency of the CRISPR/Cas system and to confirm mutation in the target locus and discusses their advantages and disadvantages. It aims to provide information that could help researchers to choose a technique most appropriate for their specific tasks and available resources.
