Cloning and expression of the Escherichia coli K-12 sad gene.

Cloning and Expression of the Coat Protein Gene of Barley Yellow Dwarf Virus-PAV in Escherichia coli

Cloning and expression of fragment of the rabies virus nucleoprotein gene in Escherichia coli and evaluation of antigenicity of the expression product

Rabies virus nucleoprotein (N protein) encapsidates genomic RNA of the virus and forms the viral ribonucleoprotein complex. These N proteins represent highly organized structures which activate proliferation of B cells and production antibodies against the N protein. In addition to the B cell, the rabies virus N protein has been shown to induce potent T helper cell responses resulting in a long...

Cloning and sequencing of ompf Salmonella typhi Salmonella ompf gene in Escherichia coli Origami

Background and Aim: Salmonella Typhi belongs to the family Enterobacteriaceae, gram-negative bacilli and causes gastrointestinal diseases such as typhoid. This bacterium has a special structure and various genes, including the ompf gene (outer membrane protein). Recent studies have shown the possibility of using ompf in the development of a diagnostic tuberculosis vaccine. Therefore, the aim of...

Cloning and optimization of phytase enzyme gene expression in Escherichia coli

Introduction Phytase is an enzyme that has the ability to break down phytic acid into myoinositol and mineral phosphate, and widely uses as an additive in animal foods. The aim of this study was to achieve a high level of bacterial phytase expression in PET26b expression host. Materials and Methods To generate the recombinant phytase enzyme, the target gene was introduced into the expression ...

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...
