Product Information

Cat. No. VAR-021
Description Lipid A is a lipid component of an endotoxin held responsible for the toxicity of gram-negative bacteria. It is the innermost of the three regions of the lipopolysaccharide (LPS), also called endotoxin molecule, and its hydrophobic nature allows it to anchor the LPS to the outer membrane. Lipid A (and LPS) has been demonstrated to activate cells via Toll-like receptor 4 (TLR4), MD-2 and CD14 on the cell surface. They are being developed as drugs for the treatment of excessive inflammatory responses to infections with gram-negative bacteria.
