Product Overview | |
| Name | OmpA |
|---|---|
| Description | |
| Outer Membrane Protein-A Bacterial Recombinant | |
| Synonyms | |
| Outer Membrane Protein-A, OmpA. | |
| Introduction | |
| The OmpA protein is one of the main outer-membrane proteins of a large array of Gram-negative bacteria such as A.salmonicida, Shigella dysenteriae and E.coli.OmpA’s major physiological functions include maintenance of the structural integrity and morphology of the cells and porin activity, as well as a role in conjugation and bacteriophage binding.Achromogenic atypical Aeromonas salmonicida is the causative agent of goldfish ulcer disease.Virulence of this bacterium is associated with the production of a paracrystalline outer membrane A-layer protein.The species specific structural gene for the monomeric form of A-protein was cloned into a pET-3d plasmid in order to express and produce a recombinant form of the protein in E.coli BL21(DE3). The induced protein was isolated from inclusion bodies by a simple solubilization-renaturation procedure and purified by ion exchange chromatography on Q-Sepharose to over 95% pure monomeric protein.Recombinant A-protein was compared by biochemical, immunological and molecular methods with the A-protein isolated from atypical A.salmonicida bacterial cells by the glycine and the membrane extraction methods. | |
| Source | |
| Escherichia Coli. | |
| Physical Appearance | |
| Sterile Filtered clear solution. | |
| Formulation | |
| PBS and 25MmM Arginine. | |
| Stability | |
| OmpA S.Enteritidis Recombinant although stable at 4°C for 1 week, should be stored below -18°C. Please prevent freeze thaw cycles. | |
| Purity | |
| Protein is >95% pure as determined by 10% PAGE (coomassie staining). | |
| Applications | |
| Immunoassay. Outer membrane protein A (ompA) of S. Enteritidis is a protein directly exposing to outsides of this organism, In hens, the production of antibodies against outer membrane protein A (ompA) during the infection has been demonstrated by inoculating both the complete bacterium and expressed protein produced from ompA DNA vaccine. Vaccination by ompA protein to hens is a poteintail tool to control S. enteritidis contaminated eggs into market, and prevent human foodborne disease from eggs. | |
| Precautions | |
| OmpA is for research use only and not for use in diagnostic or therapeutic procedures. | |
