Optimized protocols for efficient gene editing in mouse hepatocytes in vivo using CRISPR-Cas9 technology

We provide a protocol for gene editing in mouse hepatocytes in vivo using the CRISPR-Cas9 technology via AAV delivery. This protocol describes the construction of AAV plasmids, AAV packaging, injection, and the detection of in vivo knockout efficiency. Using this protocol, we can get up to 10¹⁴ AAV and knock out genes in hepatocytes efficiently within 15 days. Moreover, we describe an optimized protocol to simultaneously target two genes via AAV delivery of CRISPR-Cas9 materials in the liver. For complete details on the use and execution of this profile, please refer to Wei et al. (2020).
