BEVS is a eukaryotic system that utilizes the Autographa californica nuclear polyhedrosis virus (AcNPV) for high-level expression of recombinant proteins in Lepodoptera-derived insect cell lines, such as Sf9, Sf21, and The baculovirus expression vector system (BEVS) is a widely used platform for the production of recombinant eukaryotic proteins. However, the BEVS has limitations in comparison to other higher eukaryotic expression systems. First, the insect cell lines used in the BEVS cannot produce glycoproteins with complex‐type N‐glycosylation patterns. The insect based Baculovirus Expression Vector System (BEVS) has shown its utility in large-scale production of both proteins and viral vectors.

baculovirus system has become one of the most versatile and powerful eukaryotic vector systems for recombinant protein expression (4). More than 600 recombinant genes have been expressed in baculoviruses to date. Since 1985, when the first protein (IL-2) was produced in large scale from a recombinant baculovirus, use of BEVS has increased dramatically (5). Overview of the Baculovirus Expression System. This unit provides information on the replication cycle of insect baculovirus to provide an understanding of how this virus has been adapted for use as an expression vector for recombinant proteins in insect cells.

It is one of the most versatile and powerful systems for eukaryotic expression of recombinant proteins. This system is particularly advantageous for large-scale preparation of proteins that require expression in eukaryotic host cells. The baculovirus expression vector system (BEVS) platform has become an established manufacturing platform for the production of viral vaccines and gene therapy vectors.

A baculovirus expression vector (BEV) is a recombinant baculovirus with a double-stranded circular DNA genome that has been genetically modified to include a foreign gene of interest. BEVs are viable and can infect susceptible hosts, usually cultured lepidopteran insect cells or larvae, in a helper-independent fashion. In addition, the high level of baculovirus expression of protein will cause the speed of post-translational modification of cells to keep up with the speed of expression, which may reduce the production of post-expression modified proteins. , Baculovirus-insect cell expression system has been widely used in human health, medicine, agriculture and other fields. Baculoviruses have a biphasic (2-phased) replication cycle where they spread as either a budded virus (BV) or an occlusion-derived virus (ODV).
