Application

Lipopolysaccharides from Escherichia coli 026:B6 was used to elicit the secretion of cytokines by human PBMC[1], murine bone marrow dendritic cells[2] and rat astrocytes.[3]
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.

Questions

  1. LPS（Product number:L 2654）はTLR2に結合しますか？

    1 réponse

    1. Lipopolysaccarides from Escherichia coli O26:B6 are expected to only interact with Toll-like receptor 4 (TLR4). Similar lipopolysaccharides from Porphyromonas gingivalis have demonstrated the ability to bind with both TLR2 and TLR4. This observation is described more fully in the peer-reviewed publication, "Effects of serotype and species dependency of bacterial lipopolysaccharides in human melanocytes from lightly and darkly-pigmented skin," and in its associated citations.
