General description
This product is TCA extracted from E. coli serotype O127:B8. The source strain is ATCC 12740. This LPS serotype has been used in the study of septic shock and to induce NOS in murine macrophages and PAF synthesis in rat glomerular masangial cells.
Application
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 Actions
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.
Preparation Note
The product is soluble in water (5 mg/ml) or cell culture medium (1 mg/ml) yielding a hazy, faint yellow solution. A more concentrated, though still hazy, solution (20 mg/ml) has been achieved in aqueous saline after vortexing and warming to 70-80 oC. Lipopolysaccharides are molecules that form micelles in every solvent. Hazy solutions are observed in water and phosphate buffered saline. Organic solvents do not give clearer solutions. Methanol yields a turbid suspension with floaters, while water yields a homogeneously hazy solution.
