Endospores of Bacillus subtilis have been used extensively as a platform for recombinant protein display for nearly two decades. Main use of the spore surface display system is generation of oral vaccines against many human and animal pathogens. Formulation of oral vaccine based on spores is an attractive approach to alternative vaccination due to the timesaving and relative easiness of product...

cucumber mosaic virus (cmv) is one of widely-spread viruses of plants with the broadest host range encompassing over 1200 species. one major limiting factor for detection of the virus is unavailability of the virus-specific antibodies especially in developing countries. recombinant dna technology facilitates antibody preparation without requiring special equipment. in this study, coat protein (...

background: interleukin-27 is a heterodimeric cytokine belonging to il-12 and il-23 families, secreted  by antigen presenting cells( apcs ) .the il-27 is composed of 2 subunits: epstein-barr virus induced gene 3 (ebi3) and p28. il-27 is an anti-inflammatory cytokine which has an inhibitory effect on th17 population and suppress the il-17 expression. it is suggested that il-27 could be a potent ...

white spot syndrome virus (wssv) is a highly pathogenic and prevalent virus affecting shrimp culture worldwide including iran. in the present study, a pair of primers was designed according to the sequence of vp 28 gene of wssv in the genbank. vp28 gene from an iranian wssv isolate (irvp28) was cloned, sequenced and expressed in escherichia coli bl21(de3) strain in order to produce vp28 protein...

in order to evaluate times and rate applications of zinc fertilizer on quantity and quality of faba bean, an experiment was carried out to form factorial in randomized of complete block design with four replications at farm research of gonbad kavous university during 2009 – 2010. two times of application were including before flowering and beginning of pod setting and five rates of application ...

conclusion: the newly produced recombinant protein bmk revealed to be immunogenic. moreover, anti-bmk antibodies produced in mice were able to recognize both the recombinant bmk neurotoxin and the one in m. eupeus crude venome. taken together, the molecular characterization and recombinant production of the iranian scorpion m. eupeus venom component can serve as a new probe for further studies ...

conclusions these results demonstrated that the recombinant lysostaphin produced in this study was able to kill nasal s. aureus in rats. it can be recommended for human clinical trial studies. results recombinant lysostaphin at 100 μg/ml concentration showed a significant decrease of the optical density compared to the control samples. the in vivo study demonstrated that a single dose (200 μg/d...

turnip curly top virus (tctv) is a member of the newly established genus turncurtovirus, family geminiviridae. development of an efficient detection system is necessary to study the biological characteristics of viruses. due to the superior efficacy of the serological methods for detection of plant viruses, in this research, with the aim to facilitate the process of immunological detection of t...

The seed coat serves as a multifunctional organ with a role in protection and for the supply of nutrients to the embryo sac during development. The composition of the legume seed coat differs from other seed tissues in many ways including its protein composition. An abundant 24 kDa protein (SC24) has been purified and identified from soybean (Glycine max [L.] Merr) seed hulls. The corresponding...

background: the over-expression of recombinant proteins in large amount is important for production of therapeutic proteins and structural study. there are several systems for expression of recombinant proteins. one of the most relevant expression systems is escherichia coli (e. coli). although this organism has many advantages, most of recombinant proteins expressed in e. coli hosts form inclu...
