Abstract
A bacterial endotoxin lipopolysaccharide of reduced toxicity covalently coupled to a protein antigen exhibits enhanced adjuvant effects. The coupling was affected by reaction with haloacylhalide. Lipopolysaccharide acylated with an anhydride of a dibasic acid is detoxified; in combination with endotoxin polysaccharide covalently coupled to protein antigen it developed synergistic immunogenic effects.
