General description
Lipopolysaccharides (LPS) are intricate molecules consisting of lipids and polysaccharides, predominantly present in the outer membrane of Gram-negative bacteria. Comprising lipid A, the core oligosaccharide (core), and the O-specific polysaccharide or O antigen (OAg), LPS is anchored to the outer bacterial membrane, with lipid A primarily responsible for its associated toxicity. Functioning as a potent activator of the proinflammatory response, LPS engages various mammalian cells, including macrophages, monocytes, and endothelial cells. While serving a protective role for Gram-negative bacteria against environmental stress, LPS also triggers recognition by the innate immune system during infections.
Application
This LPS serotype has been used to stimulate B-cells and induce NOS in human hepatocytes.
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).
Biochem/physiol Actions
LPS is a major constituent of the cell wall of most gram negative bacteria. It is a highly immunogenic antigen with the ability to enhance immune responses to soluble antigens. LPS also acts as a specific mitogen for bone marrow derived B lymphocytes from mice, rabbits, chickens, cows, hamsters, and humans.
Features and Benefits
- High-purity compound suitable for a wide variety of research applications
Reconstitution
Lipopolysaccharides are supplied as lyophilized, γ-irradiated powders. To reconstitute, add 1 ml sterile balanced salt solution or tissue culture medium to the vial (1 mg) and gently swirl until the powder dissolves. Reconstituted product may be further diluted to desired working concentrations using sterile balanced salt solution or tissue culture medium.

Lipopolysaccharides or endotoxins elicit an excessive host inflammatory response and lead to life-threatening conditions such as endotoxemia and septic shock. Lipopolysaccharides trigger mobilization and stimulation of leukocytes and exaggerated production of pro-inflammatory molecules including cytokines and proteolytic enzymes. Matrix metalloproteinase-9
