The baculovirus expression vector system (BEVS) is far from new. For thirty years researchers have been using this platform to express recombinant proteins, and thousands of proteins have been successfully expressed and purified. However, for much of this time, BEVS was relegated to the ranks of research tool.

Baculovirus structure Baculovirus expression vector systems The majority of baculovirus expression systems exploit the polh promoter to drive high level production of foreign proteins. • The baculovirus polh gene is non-essential for virus replication in insect cell cultures and therefore can be removed from the virus genome with no detrimental effect to budded virus production. Baculovirus, a rod-shaped virus which infects insect cells, is used as the expression vector in this system. Insect cell lines derived from Lepidopterans (moths and butterflies), such as Spodoptera frugiperda, are used as host.

The Baculovirus Expression Vector System (BEVS) is an established method within the scientific and industrial communities for generating large quantities of recombinant protein. 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

Traditional baculovirus systems require purification and amplification of an initial low-titer viral supernatant. In contrast, the Bac-to-Bac Baculovirus Expression System is faster and easier because the technology relies on generation of recombinant baculovirus by site-specific transposition in E. coli rather than homologous recombination in insect cells, which often results in low titers. With the aim of improving the level of secretion of recombinant proteins in the baculovirus expression vector system (BEVS), we designed several signal peptides based on the signal peptide of silkworm SP1 by introducing the basic amino acid arginine into the N-terminal region and/or the polar amino acid asparagine into the C-terminal region of the silkworm SP1 signal peptide. 2018-12-12 · The baculovirus expression vector system (BEVs) derived from this virus is popular for the production of engineered proteins 11.
