The baculovirus-insect cell system is a transient expression system in which baculovirus-infected insect cells express the glycoprotein of interest for a period of ∼2 days, beginning about a day after infection, when the gene encoding the glycoprotein of interest begins to be expressed during the late or very late phase of infection. Post-translational modifications, production of protein complexes, and reported high protein yields are some of the favorable features of this eukaryotic expression system. Expression of glycoproteins in mammalian cells will result in mammalian-type glycosylation. The Baculovirus insect cell expression system is widely used for the production of precisely matured, folded and processed recombinant proteins. Baculovirus expression in insect cells represents a robust method for producing recombinant glycoproteins or membrane proteins. 28 for an excellent review). Baculovirus-Insect cell expression system is one of the most popular eukaryotic expression systems for research and industrial applications. Therefore, one should be prepared for the case that one construct fails or does not yield enough protein. There are several advantages of using baculovirus expression system over E. coli system, such as improved solubility, ability to incorporate post-translational modifications, and higher yields for secreted proteins. Baculovirus expression vector system (BEVS) is a power system to produce a variety of prokaryotic and eukaryotic protein. The baculovirus insect cell expression system is based on the use of recombinant baculoviruses (insect viruses) and their ability to produce high levels of biologically active proteins in cultured insect cells or insect larvae. AIDS 4: 1125–1131 PubMed Google Scholar Miyagawa K, Sakamoto H, Yoshida T, Yamashita Y, Mitsui Y, Furusawa M, Maeda S, Takaku F, Sugimura T, Terada M (1988) hst-1 transforming protein: expression in silkworm cells and characterization as a novel … For human proteins this is ideal, however some cell lines will add the non-human Gal α1-3 Gal epitope and the N-glycolylneuraminic acid (NGNA). [9] [10] [11] Baculovirus-produced proteins are currently under study as therapeutic cancer vaccines with several immunologic advantages over proteins derived from mammalian sources.
