Opis ogólny
This product is extracted from E. coli serotype O111:B4 and purified by chromatography. The source strain is from a private collection. The lipid A moiety has been partially delipidated by alkaline hydrolysis. Removal of the fatty acid portions of lipid A results in a detoxified LPS with an endotoxin level about 10,000 times lower than that of the parent LPS.
Zastosowanie
Lipopolysaccharides (LPSs) are characteristic components of the cell wall of Gram-negative bacteria. LPS and its lipid A moiety stimulate cells of the innate immune system by the Toll-like receptor 4 (TLR4), a member of the Toll-like receptor protein family, which recognizes common pathogen-associated molecular-patterns (PAMPs).
Działania biochem./fizjol.
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.
Uwaga dotycząca przygotowania
Chromatographically purified; delipidized by alkaline hydrolysis
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.
