Optimizing genome editing strategy by primer-extension-mediated sequencing

Efficient and precise genome editing is essential for clinical applications and generating animal models, which requires engineered nucleases with high editing ability while low off-target activity. Here we present a high-throughput sequencing method, primer-extension-mediated sequencing (PEM-seq), to comprehensively assess both editing ability and specificity of engineered nucleases. We showed CRISPR/Cas9-generated breaks could lead to...
