In this study, our previously reported novel synthetic gene encoding 166 residues of interferon-? was used for an efficient expression of IFN-?. The synthetic gene was cloned into pET21a expression vector and transferred into E. coli. Recombinant protein was over-expressed in the E. coli. Identity of the recombinant protein was confirmed by western blot analysis. The recombinant protein was bio...
diphtheria is a fatal disease caused by exotoxin of corynebacterium diphtheria . this toxin consists of two chains, catalytic chain (a) and binding (b) chain. by binding chain (b), the toxin binds to its receptor on numerous body cells such as myocardial, kidney and peripheral nerve cells. after entering, catalytic chain (a) inhibits protein synthesis and finally can cause cell dea...
b ackground: the prevalence of urinary tract infection (uti) is really high in the world. escherichia coli is a major agent of uti. one of the strategies for decreasing uti infections is vaccine development. as the attachment is a really important stage in colonization and infection, at- tachment inhibition has an applied strategy. fimh protein is a major factor during bacterial colonization i...
Background and Objective: Breast cancer is one of the most common types of cancer among women. HER-2 molecule as the receptor of tyrosine kinase from the family of epithermal growth factor is a major cause of cancer. The Herceptin protein molecule, which is an anti-HER-2 antibody, can play an important role in the diagnosis and treatment of breast cancer. This study was done to subcloning of He...
objective: escherichia coli o157:h7 is a gram-negative rod-shaped bacterium. e coli o157:h7 is an enterohemorrhagic (ehec) strain of the bacterium escherichia coli and a cause of foodborne illness. infection often leads to bloody diarrhea by producing a toxin called shiga toxin, which damages the intestines, and occasionally leads to kidney failure, especially in young children and elderly peop...
background and objectives: brucellosis is an important health problem in developing countries and no vaccine is available for the prevention of infection in humans. because of clinically infectious diseases and their economic consequences in human and animals, designing a proper vaccine against brucella is desirable. in this study, we evaluated the immune responses induced by a designed recombi...
Background: Interferon beta is one of the most important members of group I interferons and is the main drug for multiple sclerosis treatment. Interferon beta has short half life and this compels patients to make frequent use of medicine. According to its clinical usage there is broad effort to improve translation level and protein production. There are several important factors which effect pr...
Background: Recombinant proteins overexpressed in E. coli are usually deposited in inclusion bodies. Cysteines in the protein contribute to this process. Inter- and intra- molecular disulfide bonds in chitinase, a cysteine-rich protein, cause aggregation when the recombinant protein is overexpressed in E. coli. Hence, aggregated proteins should be solubilized and allowed to refold to obtain nat...
Chlamydia trachomatis is one of the main causes of Sexually Transmitted Diseases (STDs) such as prostatitis and epididymitis in men and cervicitis, endometriosis, vaginitis and ureogenital tract infections in women. Serological tests with sensitivities related to specific antigens are commonly used as routine laboratory tests for diagnosis of Chlamydia. In this research the Chlamydia Major O...
Background: Improving the performance of HIV diagnosis assays is one of the most important ways to reduce HIV transmission. Because of the high mutation rate of HIV, it is critical to use the conserved proteins to develop diagnostic immunoassay methods. Because integrase is one of the most conserved proteins of HIV, it may be a good target for this purpose. In this paper cloning, purification a...
