Anti-Pseudomonas aeruginosaLPS antibody, Mouse monoclonal

半岛bd体育手机客户端 说明

一般描述

Pseudomonas aeruginosais a rod shaped, gram negative, monoflagellated, aerobic to facultative anaerobe bacteria which commonly inhabits soil and aqueous environments.1,2P.aeruginosais considered an opportunistic human pathogen mainly causing disease in immunocompromised patients. It is especially fatal in cystic fibrosis (CF) patients, but also presents a major problem in chronic wounds, burn wounds and infection of implanted biomaterials such as catheters.3

特异性

The antibody has no cross reactivity with LPSs ofProteus mirabilis,Porphyromonas gingivalis, E. coli,Akkermansia muciniphilaorSalmonella enterica.

应用

The antibody may be used in various immunochemical techniques including ELISA and Immunoblotting. Detection of theP. aeruginosaLPS bands by Immunoblotting is specifically inhibited by the immunogen.

生化/生理作用

P. aeruginosais a major cause of nosocomial infections which affect more than 2 million patients every year and are accounted for around 90,000 deaths annually.3 It forms highly resistant biofilms on human tissues such as the lungs of CF patients or medical surfaces. OnceP. aeruginosainfection is established it is extremely hard to eradicate.3 The genome ofP. aeruginosaencodes a vast arsenal of virulence factors. However, theP. aeruginosaisolated from chronic infections expresses less virulence factors in comparison to isolates from acute infections but more readily form biofilms.1,4-6

P. aeruginosacells possess a single flagellum and type 4 pili that are important for adhesion to the host epithelial cells, motility and can also initiate an inflammatory response.1 After adhesion,P. aeruginosaactivates Type 3 secretion system (T3SS) and injects cytotoxins into the host cell.1 Moreover,P. aeruginosasecretes several proteases, which can degrade host complement, mucins, and disrupt tight junctions6-7,. In addition to lipases and phospholipases, that degrade lipids in host cell membranes6, and expresses Lipopolysaccharide (LPS), that is involved in inflammatory response and antibiotic resistance8.
Antibiotic resistance to many classes of antibiotics is a major challange inP. aeruginosatreatment.P. aeruginosapossesses several resistance mechanisms such as, low permeability of the outer membrane,
expression of membrane efflux (Mex) pumps, and β-lactamase and AmpC that hydrolases β-lactam antibiotics such as, penicillin9. In addition, as a result of genetic transfer new resistant strains emerge constantly. Therefore, finding new prevention and treatment strategies forP. aeruginosainfection is of high importance.1

外形

Supplied as a solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide as a preservative.

储存及稳定性

For continuous use, store at 2-8℃ for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours. Protect from prolonged exposure to light.
