  • Lipopolysaccharides (LPS) extracted from Escherichia coli
    Patent number: 6833451
    Abstract: Lipopolysaccharides and processes for producting the lipopolysaccharides are provided. The lipopolysaccharide has a lipid A portion, a core oligosaccharide portion, and an O-specific chain having a single repeating unit 06. A lipopolysaccharide may be produced by washing and drying and E. coli bacterial mass, subjecting the washed and dried bacterial mass to a phenol/water extraction, and treating the extract with RNases, DNases, and proteinase K.
