일반 설명
Lipopolysaccharides (LPS) are glycolipids, a combination of carbohydrate units linked with single or multiple fatty acids that are found in the cell wall of Gram-negative bacteria. The LPS is an essential component of the outer membrane and the LPS structure is composed of lipid A, a glucosamine-based phospholipid, a short-core oligosaccharide, and an O-antigen, a distal polysaccharide.
애플리케이션
Lipopolysaccharide from Escherichia coli O55:B5 has been used:
- to stimulate hepatocytes and non-parenchymal cells
- to stimulate the spleen and study the expression of the Malitaf gene in the fish blunt snout bream
- as part of the concanavalin A (ConA) and D-galactosamine/lipopolysaccharide (D-GalN/LPS) model of fulminant hepatitis to study the effect of the natural compound hesperetin
- to check the cell viability of human chorionic villi-derived mesenchymal stem cells (hCMSCs) by methyl thiazolyl tetrazolium (MTT) assay
- to induce oligodendrocyte toxicity to evaluate the neuroprotective effects of few compounds
- to induce sarcopenia in rats to evaluate the antioxidant effects of curcumin-loaded hydrophobic surface-modified hydroxyapatite
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).
생화학적/생리학적 작용
Lipopolysaccharides (LPS) sets up a protective permeability barrier that blocks the entry of antibiotics and bile salts, which make Gram-negative bacteria innately resistant. LPS is involved in bacterial pathogenicity as the host immune system primarily encounters the LPS component of the bacteria. LPS is an endotoxin and a highly immunogenic antigen that can enhance the immune system. The lipid A of LPS stimulates host cells via toll-like receptors 4 (TLR4).

For optimal reconstitution of LPS products, an intensive vortex is required before use, regardless of the container type. Ensure that the storage solution concentration is at least 1 mg/ml. While borosilicate (silanized) containers are recommended, polypropylene (PP) plastic containers may also be used.
