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.

Earlier, we reported that pathogen-associated molecular patterns such as lipopolysaccharide (LPS), when administered intratracheally (i.t.), affected primary and secondary specific antibody responses to antigens administered concurrently, either i.t. or systemically, and also affected BW gain (BWG) of layers and broilers.
