Application

Lipopolysaccharides from Escherichia coli 0127:B8 has been used:
  • to study the LPS-induced macrophage survival in mice
  • to elicit the secretion of cytokines by cattle PBMC
  • to study apoptosis of highly susceptible macrophage cells in a LPS-induced proinflammatory environment
  • to perform autophagy assay in BV2 and BV2-LC3 cells
  • for stimulation of human monocytes, macrophages and mouse microglia cells
  • to induce pentraxin-3 expression in 293T cells
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

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). Being an immunogenic antigen, it enhances immune responses to soluble antigens.

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.

Several G-protein-coupled receptors (GPCRs) have been shown to be important signaling mediators between neurons and glia. In our previous screening for identification of nerve injury-associated GPCRs, G-protein-coupled receptor 84 (GPR84) mRNA showed the highest up-regulation by microglia after nerve injury.
