Lipopolysaccharides from Escherichia coli O26:B6
SIGMA/L2654 - γ-irradiated, BioXtra, suitable for cell culture
Synonym: LPS
CAS Number: 93572-42-0
EC Number: 297-473-0
MDL Number: MFCD00164401
Product Type: Chemical
Lipopolysaccharides (LPS) are localized in the outer layer of the membrane and are, in noncapsulated strains, exposed on the cell surface. They contribute to the integrity of the outer membrane, and protect the cell against the action of bile salts and lipophilic antibiotics.

| Application: | 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). |
| 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. |
| 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. |
