Dear Colleagues, It is my pleasure to invite you to submit an original or review article for publication in a Special Issue on “Lipopolysaccharide: Bacterial Endotoxin”. 2017-03-06 · What is Low Endotoxin/Lipopolysaccharide recovery (LER/LLR)? Although LAL is a powerful assay to detect the presence of endotoxin at very low levels, concerns have grown in the recent past when measurable endotoxin concentration was found in decline over time (such as during storage) in products or in-process materials despite the fact that the samples may maintain pyrogenicity in the USP Endotoxin is continuously shed from the outer membrane of viable gram-negative bacteria and is released when the bacterial cell dies.

Our lipopolysaccharides contain endotoxin levels of not less than 500,000 EU (endotoxin units)/mg unless otherwise noted.

Endotoxins are lipopolysaccharides (LPS) derived from cell membrane of Gram- negative bacteria and are responsible for its organization and stability.

▪ Abstract Bacterial lipopolysaccharides (LPS) typically consist of a hydrophobic domain known as lipid A (or endotoxin), a nonrepeating “core” oligosaccharide, and a distal polysaccharide (or O-antigen). Endotoxin from gram-negative bacteria in the gut lumen enters the body either as a component of the whole organism or as polymers of free lipopolysaccharide (LPS).
