Baculovirus expression is a time-tested technique to produce proteins in insect cells, in high quality and quantity for a range of applications. MultiBac is a baculovirus expression system we developed originally for producing multiprotein complexes comprising many subunits, for structural and mechanistic studies. First introduced in 2004, MultiBac is now in use in many laboratories worldwide, accelerating research programmes in academia and industry. We have continuously optimized our MultiBac system, providing customized reagents and standard operating protocols to facilitate its use also by non-specialists. More recently, we have generated MultiBac genomes tailored for specific purposes, for
example, to produce humanized glycoproteins, high-value pharmaceutical targets including kinases, viral polymerases, and virus-like particles (VLPs) as promising vaccine candidates. By altering the host tropism of the baculovirion, we created MultiBacMam, a heterologous DNA delivery toolkit to target mammalian cells, tissues and organisms. Introducing CRISPR/Cas modalities, we set the stage for large-scale genomic engineering applications utilizing this high-capacity DNA delivery tool. Exploiting synthetic biology approaches and bottom-up design, we engage in optimizing the properties of our baculoviral genome, also to improve manufacturing at scale. Here we provide a perspective of our MultiBac system and its developments, past, present and future.
