there are many studies related to the production of a elisa kit for diagnosing virus infections. however, production of most kits depends on purification of whole virus particles, which involves the use of costly equipment and reagents. the purpose of this study was to check out if the anti-cp42 antibodies could be used as a diagnostic assay for detection of grapevine fanleaf virus (gflv). in t...
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 ...
Potato leafroll virus is a member of the polerovirus genus. The isometric virion is formed by a coat protein encapsidating single-stranded, positive-sense, mono-partite genomic RNA with covalently attached viral protein at the 5' end. The coat protein of the virus exists in two forms: i) a 23 kDa protein, the product of the coat protein gene, and ii) a 78 kDa protein, the product of the coat pr...
Background and Amis: Serological assay is considered as one of the best choices for conducting large number of infection tests. Recombinant DNA technology has been used for expression of virus coat protein (CP) gene in prokaryotic bacterial cells such as Escherichia coli and the recombinant CP (rCP) is used as immunogen in antibody production. Heterologous CP protein expression and purification...
Pelargonium zonate spot virus (PZSV) is identified recently in tomato plants in the United States. To develop serological diagnostic tools for the detection of this virus, the production of good quality antibodies is a necessity. The coat protein (CP) gene of a California isolate of PZSV was cloned into a bacterial expression vector (pTriEX-4 Ek/LIC). The plasmid pTriEX-4-PZSV-CP was transforme...
Here we report on the conformational changes that are responsible for the appearance of the Dicentrarchus labrax encephalitis virus (DlEV) coat protein as a doublet in SDS-PAGE. Wild-type and mutated forms of the coat protein cDNA were expressed in E. coli. The study of the resulting recombinant molecules excluded the possibility of the involvement of a precursor autocatalysis mechanism or a ri...
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...
conclusions based on the findings, application of recombinant arcaga antigen for the detection of h. pylori infection is a simple, rapid, and brief non-invasive method. therefore, it can be suggested as an appropriate antigen for h. pylori detection kits. results we investigated caga protein, using the immunoblotting method in stool samples, which were already identified as positive by the appl...
Secretory proteins are transported from the endoplasmic reticulum (ER) in vesicles coated with coat protein complex II (COPII). To investigate the molecular mechanism of protein sorting into COPII vesicles, we have developed an in vitro budding reaction comprising purified coat proteins and cargo reconstituted proteolipsomes. Emp47p, a type-I membrane protein, is specifically required for the t...
