  • Preparation for treatment of allergic patients sensitive to ragweed pollen
    Patent number: 4269764
    Abstract: The preparation of this invention comprises ragweed antigens polymerized with glutaraldehyde which are composed essentially of water-soluble polymers of molecular weights from 200,000 to 20,000,000.
    Type: Grant
    Filed: June 27, 1980
    Date of Patent: May 26, 1981
    Inventors: Roy Patterson, Floyd C. McIntire
  • Chemically modified endotoxin immunizing agent
    Patent number: 4185090
    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.
    Type: Grant
