LIPOPOLYSACCHARIDE (LPS) EXTRACTED FROM ESCHERICHIA COLI

摘要

The invention relates to lipopolysaccharides extracted from E. coli DSM 6601. This LPS differs from the known LPS extracted from E. coli in particular with regard to the phosphorylated sugar moiety of the core and to the degree of polymerization of the O-chain. The A lipoid corresponds structurally and biologically to the classic type of E. coli. The inventive LPS is not only suitable for identifying the coli strain which carries it, but also provides the latter with a reduced pathogenic capability, whilst retaining its immunomodulative effect.
