Influenza virus is a continuous and severe global threat to mankind. The continuously re-emerging disease gives rise to thousands of deaths and enormous economic losses each year, which emphasizes the urgency and necessity to develop high-quality influenza vaccines in a safer, more efficient and ..., Abstract

As a protein expression vector, the baculovirus demonstrates many advantages over other vectors. With the development of biotechnology, baculoviral vectors have been genetically modified to facilitate high level expression of heterologous proteins in both insect and mammalian cells. These ..., Abstract

Crimean-Congo Haemorrhagic Fever Virus (CCHFV) is a tick-born virus of the Nairovirus genus within the Bunyaviridae family, which is widespread and causes high fatality. The nucleocapsid of CCHFV is comprised of N proteins that are encoded by the S segment. In this research, the N protein of CCHFV ..., Abstract

The Crimean-congo hemorrhagic fever virus (CCHFV) is a geographically widespread fatal pathogen. Identification of the epitope regions of the virus is important for the diagnosis and epidemiological studies of CCHFV infections. In this study, expression vectors carrying series truncated fragments ..., Abstract

p10 is one of the two very late genes that are highly expressed in baculovirus infected cells. We have studied the function of P10 by constructing a p10 deletion recombinant of the Helicoverpa armigera singly-enveloped nucleopolyhedrovirus (HaSNPV). The p10 gene of HaSNPV bacterial artificial ..., Abstract

The transcription profiles of nine selected HaSNPV genes, e.g. early phase genes, early and late phase genes, late phase genes and very late phase genes were analyzed using reverse transcription and real-time quantitative PCR. The results indicated that for most of these genes ..., Abstract

Genes encoding nucleocapsid (N) and envelope (E) proteins of SARS coronavirus (SARS-CoV) were obtained by RT-PCR and were cloned into the expression vector pGEX-KG. The genes were expressed in E. coli and the recombinant proteins were in a soluble form. The proteins were purified by affinity ..., Abstract

The cDNA and genomic DNA of ribosomal protein L13 (RpL13) gene were cloned from Helicoverpa zea cells(HzAM1). Sequence analysis indicated that the open reading frame of rpL13 was composed of 666bp without intron,encoding a protein of 25 kDa. The sequence was used to construct phylogentic trees with ..., Abstract

To test if the foreign gene of a recombinant baculovirus can be transferred to organisms in the same ecological niche, two experiments were performed. First, the fungus Verticillium dahliae Lleb. was cultivated for up to 90 days in laboratory in the presence of BV,ODV and DNA of recombinant ..., Abstract

There are two kinds of membrane fusion proteins encoded by baculovirus: GP64 and F protein. The membrane fusion protein of group I NPV is GP64, while group II NPV is F protein. In this paper. we tried to answer whether GP64 can be expressed and assembled into the BV of Group II NPV. By using ..., Abstract

The PCR product of Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus HaSNPV fp25k gene was cloned into a prokaryotic expression vector pProEXHTb. After inducing with IPTG, the fp25k gene was successfully expressed in E.coli DH5α. The expression product was 32 kDa. This protein was ..., Abstract

The conotoxinlike (ctl) gene is a small gene in the genomes of several baculoviruses. The biological function of baculoviral ctl gene remains unknown. In this report, we generated a recombinant AcMNPV(AcBac-ph-ctl) which contains the ctl gene from BusuNPV using AcMNPV bacmid system. The ..., Abstract

The polyhedrin gene of the Heliothis armigera single nucleocapsid nucleopolyhedrovirus (HaSNPV) was localized by Southern blot hybridization with a probe from the Autographa cali-fornica MNPV (AcMNPV) polyhedrin gene. Nucleotide sequencing showed the open reading frame of the HaSNPV polyhedrin gene ..., Abstract
