Descrizione generale
This product is extracted from E. coli serotype O111:B4 and purified by ion exchange. The source strain is from a private collection. This LPS serotype has been used to stimulate B-cells and induce NOS in human hepatocytes.
Applicazioni
I lipopolisaccaridi (LPS) sono componenti caratteristici della parete cellulare dei batteri gram negativi. Il LPS e la sua frazione lipide A stimolano le cellule del sistema immunitario innato attraverso il recettore Toll-like 4 (TLR4), un elemento della famiglia delle proteine recettoriali Toll-like, che riconosce i profili molecolari associati ai patogeni (PAMP) comuni.
Azioni biochim/fisiol
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 sulla preparazione
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 °C. 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.
