BackgroundAlthough the traditional Escherichia coli expression system has matured and is cost-effective, the posttranslation modifications of proteins expressed in eukaryotic cells differ significantly from those expressed in E coli. Insect cells have gradually entered the realm of researchers; however, the proteins synthesized by insect cells are somewhat different from those of mammals in terms of modification.ObjectiveHerein, we have introduced a relatively new method. MultiBac, We introduce the development process, characteristics, and applications of MultiBac technology. And provide new methods for basic researchers.DiscussionMultiBac has evolved into an indispensable tool in the fields of biotechnology and pharmaceuticals, facilitating the efficient production of recombinant proteins and the study of complex protein complexes. Furthermore, its development has benefited from the integration of synthetic biology techniques, providing additional versatility. But it also has some disadvantages.ConclusionMultiBac technology is poised to become a key tool in unlocking the mysteries of the protein world, propelling the life sciences ever forward. But researchers should consider its limitations when selecting the most appropriate expression system for their specific needs.Copyright © 2024 the Author(s).
