Lipopolysaccharides of Helicobacter pylori strains P466 and MO19: structures of the O antigen and core oligosaccharide regions.

Lipopolysaccharides (LPS) from phenol-water extraction of dyspeptic (P466) and asymptomatic (MO19) strains of Helicobacter pylori were each isolated as water-soluble material of high relative molecular mass (high M(r)) and as water-insoluble gels of low M(r). Chemical and spectroscopic analyses of the soluble LPS and oligosaccharides liberated from the… CONTINUE READING
