Virus-Like Particles as a Nonviral CRISPR/Cas Editing Delivery Tool.

Virus-like particles (VLPs) are self-assembling viral protein complexes that mimic native virions while lacking replicative and infectious capacity. By retaining efficient cellular entry and cargo protection, they overcome key limitations of viral vectors, including insertional mutagenesis and strong immunogenicity. Their ease of production, flexible cargo capacity, and tunable tropism make them highly versatile tools. Here, we describe a protocol for generating VSV-G-pseudotyped VLPs that deliver CRISPR/Cas9 RNPs and their functional validation in surrogate cell lines.
