Descrizione generale
This product is extracted from E. coli serotype O127:B8 and purified by ion exchange. 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.
Applicazioni
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).
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.

Neuroinflammation in utero may result in life-long neurological disabilities. Microglia play a pivotal role, but the mechanisms are poorly understood. No early postnatal treatment strategies exist to enhance neuroprotective potential of microglia. We hypothesized that agonism on α7 nicotinic acetylcholine
