Beschreibung

Allgemeine Beschreibung

This product is a 0.2 um filtered aqueous solution containing 1 mg/mL of lipopolysaccharides (LPS) from E. coli serotype O26:B6. This LPS serotype has been used in studies of septic shock.

Anwendung

Lipopolysaccharide (LPS) sind charakteristische Bestandteile der Zellwand von gramnegativen Bakterien. LPS und seine Lipid-A-Gruppe stimulieren Zellen des angeborenen Immunsystems durch den Toll-like-Rezeptor 4 (TLR4). TLR4 gehört zur Toll-like-Rezeptor-Proteinfamilie, die häufige Pathogen-assoziierte molekulare Strukturen (PAMPs) erkennt.

Biochem./physiol. Wirkung

Lipopolysaccharides (LPS) are localized in the outer layer of the membrane and are, in noncapsulated strains, exposed on the cell surface. They contribute to the integrity of the outer membrane, and protect the cell against the action of bile salts and lipophilic antibiotics.

Angaben zur Herstellung

The LPS used to prepare the solution have been phenol-extracted and chromatographically purified by gel filtration. Lipopolysaccharides prepared by phenol extraction contain up to 60% RNA and less than 1% protein. Subsequent purification by gel filtration chromatography removes much of protein present in the phenol-extracted LPS, but leaves a product that still contains 10-20% nucleic acids. Further purification using ion exchange chromatography yields an LPS product which contains <1% protein and <1% RNA.
