Expression Cloning of Recombinant Escherichia coli lacZ Genes Encoding Cytoplasmic and Nuclear P-galactosidase Variants

Objective(s) Nonviral vector can be an attractive alternative to gene delivery in experimental study. In spite of some advantages in comparison with the viral vectors, there are still some limitations for efficiency of gene delivery in nonviral vectors. To determine the effective expression, the recombinant Escherichia coli lacZ genes were cloned into the different variants of pcDNA3.1 and the...

Cloning and evaluation of gene expression and purification of gene encoding recombinant protein containing binding subunit of coli surface antigens CS1 and CS2 from Enterotoxigenic Escherichia coli

Background & Objective: Enterotoxigenic Escherichia coli (ETEC) is a major causative agent of diarrhea. Enterotoxins and the colonization factors (CFs) are major virulence factors in ETEC infections. The bacterium binds to the intestinal epithelial cell surface through colonization factors and produces enterotoxins that cause excessive fluid and electrolyte secretion in the lumen of the intesti...

Cloning and Expression of Com1 and OmpH Genes of Coxiella burnetii in Periplasmic Compartment of Escherichia coli with the Aim of Recombinant Subunit Vaccine Production

Coxiella burnetiiis an obligate and gram-negative bacteria causing query fever (Q fever) disease, despite the importance of Q fever, there is no universal vaccine against this disease. Therefore, application of the recombinant subunit vaccines which use Com1 and OmpH as immunogenic proteins can be useful in this regard. To perform the current project, Com1 an...

Cloning and Expression of Mannheimia haemolytica PlpE Gene in Escherichia coli and its Immunogenicity Assessment

Mannheimia haemolytica is responsible for considerable economic losses to cattle, sheep, and goat industries in many parts of the world. This bacterium isone of the causative agents of shipping fever in cattle. Current vaccines against M. haemolytica are moderately efficacious since they do not provide complete protection against the disease. Production of a...
