Background: The importance of viral protein-2 (VP2) of canine parvovirus (CPV) in binding to human cancer cells, production of veterinary vaccines and diagnostic kits has motivated several researches on producing this protein.Objectives: Our purpose was to construct recombinant bacmid shuttle vectors expressing VP2 of CPV using Bac-to-Bac baculoviral expr...
BACKGROUND Crimean-Congo hemorrhagic fever virus (CCHFV) is a member of the nairovirus, a genus in the Bunyaviridae family, which causes a life threatening disease in human. Currently, there is no vaccine against CCHFV and detailed structural analysis of CCHFV proteins remains undefined. The CCHFV M RNA segment encodes two viral surface glycoproteins known as Gn and Gc. Viral glycoproteins can ...
BACKGROUND Sequence variations in glycoproteins of influenza virus surface impel us to design new candidate vaccines yearly. Ectodomain of influenza M2 protein is a surface and highly conserved protein. M2e in influenza vaccines may eliminate the need for changing vaccine formulation every year. OBJECTIVES In this study, a recombinant baculovirus containing M2e and cholera toxin subunit B fus...

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...
results primary, secondary, and 3d structure of cchfv gn were obtained and pcr reaction with m13 forward and reverse primers confirmed the generation of recombinant bacmid dna harboring gn coding region under polyhedron promoter. conclusions characterization of the detailed structure of cchfv gn by bioinformatics software provides the basis for development of new experiments and construction of...
Non-replicating virus-like particles (VLPs) have been suggested as a promising platform for viral vaccines. Recently several studies have introduced VLPs produced in insect cells as a vaccine candidate against influenza infection. Neuraminidase (NA), one of the two membrane glycoproteins of influenza A viruses has been employed to construct such influenza VLPs to induce protective immunity. In ...

The bacmid system of BmMNPV with cysteine protease gene deletion (CPD-BmMNPV bacmid) was constructed using the lambda recombination system. The protease activities of Bombyx mori cells and silkworm larvae infected with this CPD-BmMNPV bacmid were reduced by 94% and 85%, respectively. By using this system, a GFP(uv)-beta1,3-N-acetylglucosaminyltransferase 2 (GFP(uv)-beta3GnT2) fusion protein was...
Repeated baculovirus infections in cultured insect cells lead to the generation of defective interfering viruses (DIs), which accumulate at the expense of the intact helper virus and compromise heterologous protein expression. In particular, Autographa californica multicapsid nucleopolyhedovirus (AcMNPV) DIs are enriched in an origin of viral DNA replication (ori) not associated with the homolo...
