Epitope-G1 of bovine ephemeral fever virus (BEFV) G glycoprotein has been genetically and antigenically conserved among various isolates of BEFV and only reacts with anti-BEFV neutralising antibodies. Therefore, it is a candidate antigen for development of the enzyme linked immunosorbent assay (ELISA) for serological identification bovine ephemeral fever (BEF)-infected animals. The aim of this ...

Bovine ephemeral fever is an acute and arthropod-borne viral disease of cattle and water buffalo which occurs seasonally in most of the world tropical and subtropical regions. The epizootic feature of the disease has been reported in Iran with serious economic consequences. The surface glycoprotein G of bovine ephemeral fever virus (BEFV) is composed of 4 antigenic sites (G1-G4) and plays the m...

bovine ephemeral fever (bef) is an acute epidemic disease in cattle and water buffalo, spanning tropical and subtropical zones of asia, australia, and africa. in recent years, bef has been distributed in many provinces of iran and caused economic losses. in this study the sequence encoding the g1 epitope of bovine ephemeral fever virus (befv) g glycoprotein was amplified by pcr, ligated into th...

The main aim of this study was to obtain the Crimean-Congo hemorrhagic fever virus (CCHFV) glycoprotein, through either stable transgenic plants or using a transient expression system, and determine the yield, quality and finally the immunogenicity of the plant-made CCHFV glycoprotein in a mouse model. We designed and synthesized a codon-optimized G1/G2 gene from the G1 and G2 parts of the CCHF...

background: regarding that accurate diagnosis of human hydatidosis still needs more investigations, the present study was conducted to clone, express, and evaluate the gene encoding agb subunits (egagb16 kda) from echinococcus granulosus (iranian g1 strain) and its evaluation by elisa test. methods: dna was extracted from protoscoleces and was utilized by pcr for strain identification. total rn...

the main aim of this study was to obtain the crimean-congo hemorrhagic fever virus (cchfv) glycoprotein, through either stable transgenic plants or using a transient expression system, and determine the yield, quality and finally the immunogenicity of the plant-made cchfv glycoprotein in a mouse model. we designed and synthesized a codon-optimized g1/g2 gene from the g1 and g2 parts of the cchf...

recombinant protein purification is a kind of sensitive and expensive method in genetics engineering. genetic manipulation leads to the expression of various proteins; it should be isolated with high purity finally. differed methods for protein purification are categorized, based on cast, quality, easy work and side effect of protein. in this article, we are investigating his his-tag protein pu...

results the results showed that sensitivity and specificity were respectively 84.12% and 92% for‎ recombinant protein srs3 and 92% and 96% for rsag1. conclusions recombinant proteins srs3 and rsag1 are promising antigens in diagnostic assays for detection of specific antibodies against t. gondii. background infections by the protozoan parasite toxoplasma gondii (t. gondii) are widely prevalent ...

a sweet water-soluble protein that reminds stable over wide ranges of temperature and ph, brazzein has various applications. its tastes like cane sugar but have no calories. however, the extraction of brazzein from its natural source is expensive and not applicable. in this study we used recombinant dna technology to provide an alternative option for cheaper mass production of brazzein. a brazz...

recombinant human interferon alpha 2a (rhifn α -2a) production and cell growth were monitored in a set of genetically modified e. coli strains (msd1519, msd1520, msd 1521, msd 1522, msd 1523) producing rhifn α -2a. the growth was followed at od 600 nm, changes in cell physiology were detected by pyrolysis mass spectrometry (pyms) of cell biomass and recombinant protein production was determined...
