title: Structural studies of the O-chain of the phenol-phase soluble lipopolysaccharide from Haemophilus pleuropneumoniae serotype 2.
abstract: The phenol-phase soluble cellular lipopolysaccharide that was isolated by the phenol-water extraction from Haemophilus pleuropneumoniae serotype 2 was shown to be of the S type by sodium dodecyl sulfate--polyacrylamide gel electrophoresis, hydrolysis, methylation, specific degradations, and both one- and two-dimensional 1H and 13C nuclear magnetic resonance studies. It could be cleaved to yield a lipid A and an O-chain polysaccharide. This O-polysaccharide was identified as a high molecular weight unbranched linear polymer of a pentasaccharide repeating unit having the structure: (Formula: see text).
