Application

Lipopolysaccharides from Escherichia coli 026:B6 was used to elicit the secretion of cytokines by human PBMC, murine bone marrow dendritic cells and rat astrocytes.
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).

Actions biochimiques/physiologiques

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.

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.

Adaptive immunity is triggered at the immune synapse, where peptide-major histocompatibility complexes and costimulatory molecules expressed by dendritic cells (DCs) are physically presented to T cells. Here we describe transmission of the inflammatory monoamine serotonin (5-hydroxytryptamine [5-HT]) between these cells.
