Descrição geral
This product is TCA extracted from E. coli serotype O55:B5. The source strain is CDC 1644-70. The LPS O55:B5 has been used to stimulate human peritoneal macrophages at 1 ng/ml and to stimulate equine peritoneal macrophages at 1-100 ng/ml.
Aplicação
Os lipopolissacarídeos (LPSs) são componentes característicos da parede celular de bactérias gram negativas. Os LPS e sua porção lipídica A estimulam as células do sistema imunológico inato através do receptor do tipo Toll 4 (TLR4), um membro da família de proteínas do receptor do tipo Toll 4 que reconhece patógenos comuns associados a padrões moleculares (PAMPs).
Ações bioquímicas/fisiológicas
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.
Nota de preparo
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.
