Streptococcus iniae is a major cause of serious bacterial infections in both fish and human beings. Capsular polysaccharide (CPS) of S. iniae is vital to evade phagocytic clearance of the host and serves as an important protective antigen of S. iniae infection in aquatic animals. The CpsD gene was determined to be highly conservative in capsule polysaccharide operon. Prokaryotic expression of t...

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...

detection of plasmodium vivax specific antibodies with serological tests could be a valuable tool for epidemiological researches. whereas p. vivax cannot be simply obtained in vitro, serological tests using total or semi-purified antigens are infrequently used. given this restriction, the present study investigated whether recombinant p. vivax merozoite surface protein 1 (pvmsp-1 42 kda) could ...

background and aims: virus-like particles (vlps) have been suggested to be a promising recombinant vaccine approach. several studies have reported that the influenza vlps produced in insect cells is an effective vaccine candidate. due to crucial role of matrix m1 protein in assembly and budding of influenza particles, in all vlps structures, m1 protein have been considered as a main component. ...

Tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. On the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant E. coli, and consequently fed-batch culture have received less attention....

background: designing novel therapeutic agents has been a critical challenge for hiv disease. materials and methods: in current study a dna sequence which was encoded the tat protein was synthesized and inserted in pet 28 vector. vector was cloned in bl21-de3 e. coli and cultured in tb media. after protein expression, recombinant tat protein was purified by nta affinity chromatography. the tat ...

Bakground: Granulocyte colony-stimulating factor (G-CSF) is a cytokine that stimulates hematopoiesis and induces proliferation and differentiation of granulocyte progenitor cells as well as production of bone marrow neutrophilic granulocyte colonies.  Nowadays, human recombinant G-CSF(hr G-CSF)is used for the treatment of chemotherapy- and radiotherapy-induced neutropenia, and also in patients ...

Background: Human granulocyte colony-stimulating factor (hG-CSF) can serve as valuable biopharmaceutical for research and treatment of the human blood cancer. Transplastomic plants have been emerged as a new and high potential candidate for production of recombinant biopharmaceutical proteins in comparison with transgenic plants due to extremely high level expression, biosafety and many other a...

Recombinant methionyl human leptin (r-metHuLeptin) was first used as a replacement therapy in patients bearing inactivating mutations in the leptin gene. In this indication, it was shown since 1999 to be very efficient in inducing a dramatic weight loss in rare children and adults with severe obesity due to the lack of leptin. These first clinical trials clearly showed that r-metHuLeptin acted ...
