Protocol for non-invasive delivery of CRISPR RNPs via virus-like particles for mouse model generation

초록

CRISPR-virus-like particle (VLP)-induced targeted mutagenes is (CRISPR-VIM) enables genome editing in mouse embryos through non-invasive delivery of CRISPR ribonucleoproteins (RNPs) via VLPs, eliminating the need for physical manipulation and specialized expertise. We detail protocols for VLP production, titration, and treatment for diverse genome edits. This protocol is compatible with zygotes and in vitro fertilization (IVF)-derived embryos via simple co-culture, facilitating high-efficiency and heritable mutations with minimized off-target effects, independent of specialized equipment and conducive to reduced animal use. For complete details on the use and execution of this protocol, please refer to Jeong et al.1
