antigenic phenol-phase soluble lipopolysaccharide isolated from brucella abortus 1119-3 by hot phenol-water extraction was shown by sodium dodecyl sulfate-polyacrylamide gel electrophoresis , controlled hydrolysis , periodate oxidation , methylation , and 1h and 13c nuclear magnetic resonance studies to be an s-type lipopolysaccharide which could be cleaved to yield a lipid a and an o-chain polysaccharide identified as an unbranched linear homopolymer of 1,2-linked 4,6-dideoxy-4-formamido-alpha-d-mannopyranosyl residues .
