Baculovirus expression vectors are widely used for expressing heterologous proteins in cultured insect cells. Recent advances include further development of the system for production of multi-subunit protein complexes, co-expression of protein-modifying enzymes to improve heterologous protein production, and additional applications of baculovirus display technology. The application of modified ...

background: rotaviruses cause diarrhea in infants and young children worldwide. rotavirus outer capsid protein, vp7 is major neutralizing antigen that is important component of subunit vaccine to prevent rotavirus infection. many efforts have been done to produce recombinant vp7 that maintain native characteristics. we used baculovirus expression system to produce rotavirus vp7 protein and to s...

Here we describe the development of a baculovirus vector expression cassette containing rearranged baculovirus-derived genetic regulatory elements. This newly designed expression cassette conferred significant production improvements to the baculovirus expression vector system (BEVS), including prolonged cell integrity after infection, improved protein integrity, and around 4-fold increase in r...

The purpose of this study is to establish a gene delivery system for interstitial tissue-specific protein expression in mice testes using modified recombinant baculovirus. Green fluorescent protein (GFP)-expressing recombinant baculovirus (GFP-baculovirus), in which the insect cell-specific polyhedron promoter was replaced by the cytomegalovirus (CMV)-IE promoter, was used to transfect testicul...

By using a baculovirus expression system, the adenovirus (Ad) DNA polymerase was purified to homogeneity and shown to display a 3'-->5'exonuclease activity which is coupled to the polymerase activity. On a partial duplex structure the exonuclease activity had a marked preference for excision of a mismatched versus a matched 3'-terminus, which enables the Ad DNA polymerase to act as a proofreadi...

BACKGROUND Baculovirus expression system is one of the most attractive and powerful eukaryotic expression systems for the production of recombinant proteins. The presence of a biomarker is required to monitor transfection efficiency or protein expression levels in insect cells. METHODS The aim of this study was to construct a baculovirus expression vector encoding a copepod super green fluore...

The baculovirus expression system is one of the most successful and widely used eukaryotic protein expression methods. This short review will summarise the role of bacterial artificial chromosomes (BACS) as an enabling technology for the modification of the virus genome. For many years baculovirus genomes have been maintained in E. coli as bacterial artificial chromosomes, and foreign genes hav...

Background and Aims: Each year, the influenza virus causes moderate to severe infections with a high prevalence throughout the world. Accordingly, an influenza vaccine that ensures protection with only a single dose would be a much more cost effective approach to influenza prophylaxis. Generation of Influenza non-replicating virus-like particles (VLP) in baculoviral expression system is an attr...
