Cas9 associated sequencing (HAT-seq and Cas9-induced Indel detection)

The CRISPR (clustered regulatory interspaced short palindromic repeats)/ Cas9 (CRISPR-associated protein 9) system-based precise genome editing has revolutionized biomedical studies. As the CRISPR/Cas9 system has been also recently considered to permanently cure genetic diseases via human germline genome editing, a careful risk assessment of this genome engineering tool is required in human early development. Here we perform comprehensive analysis to evaluate the potential impact of Cas9 in human early embryogenesis.
