taq dna polymerase is widely used in laboratories and for this reason many investigators have focused their attention on understanding the role of various regions and amino acids in this enzyme. o-helix is a part of taq polymerase suggested to play an important role in the enzyme fidelity. the influence of asn666 in this helix on the enzyme function has never been investigated, and therefore by...
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...
Colistin resistance in Acinetobacter spp. is increasing, resulting potentially untreatable nosocomial infections. Plasmid-mediated colistin of particular concern due to its low fitness cost and potential transferability other bacterial strains species. This study investigated the mechanism a clinical nosocomialis isolate from Cape Town, South Africa. A colistin-resistant A. was identified blood...
background: tuberculosis (tb) remains as a major cause of death around the world. construction of a new vaccine against tuberculosis is an effective way to control it. several vaccines against this disease have been developed. the aim of the present study was to cloning of tb10.4 gene in pcdna3.1+ plasmid and evaluation of its expression in eukaryotic cells. methods: firstly, tb10.4 fragment wa...
Introduction: Multiple sclerosis (MS) is a disease of the immune system: it attacks the myelin around the axons and leaves them exposed. Destruction of myelin weakens the electrical conduction of ions and thus leads to a lack of communication in the nervous system. Methods: In the present study, we constructed recombinant plasmid and then transformed to E. coli cell. The colonies containing...
Introduction: Escherichia coli (E.coli) is one of the most widely used hosts for the production of recombinant proteins. The main problem in getting high product yields and productivity is the accumulation of acetic acid (acetate) as an unwanted metabolic by-product. In this study, an antisense-based strategy as a metabolic engineering approach was employed to hamper the acetate excretion probl...
Background: DNA immunization is an appropriate method to produce an immunological response. Pseudomonas aeruginosa produces exotoxin A which is highly cytotoxic for eukaryotic cells. Since domains II (translocation domain) and 1b of the toxin have antigenic qualities, so they could be useful candidates to protect against pseudomonas infections. Objectives: To evaluate if recombinant plasmid co...
Background: Tuberculosis (TB) remains as a major cause of death around the world. Construction of a new vaccine against tuberculosis is an effective way to control it. Several vaccines against this disease have been developed. The aim of the present study was to cloning of tb10.4 gene in pcDNA3.1+ plasmid and evaluation of its expression in eukaryotic cells. ...
Background and Aims: The aim of this study was cloning and expression of rabies virus glycoprotein by a eukaryotic expression plasmid pcDNA3.1(+) in BSR cell line. This construct might be used for a potential DNA vaccine. Materials and Methods: Glycoprotein gene was synthesized and cloned into pBluescript vector and then sub cloned into eukaryotic expression vector (pcDNA3.1(+)). After verifica...
conclusions the results of this study demonstrated that the p450 cyp141 gene was successfully cloned into a pet26b plasmid vector as an expression vector. in this paper, for the first time in iran, this gene was cloned for more purposes, including the expression and purification of the recombinant cytochrome p450 cyp141 protein. results the cloning of p450 cyp141 gene was confirmed by the enzym...
