Efficient genome editing by using CRISPR technologies requires simultaneous and efficient delivery of multiple genetically encoded components to mammalian cells. Amongst all editing approaches, prime editing (PE) has the unique potential to perform seamless genome rewriting, in the absence of DNA double-strand breaks (DSBs). The cargo capacity required for efficient PE delivery to mammalian cells stands at odd with the limited packaging capacity of traditional viral delivery vectors. By contrast, baculovirus (BV) has a large synthetic DNA capacity and can efficiently transduce mammalian cells. Here we describe a protocol for the assembly of baculovirus vectors for multiplexed prime editing in mammalian cells.
