Abstract
Polysaccharide-protein conjugates were synthesized utilizing polysaccharide derived from hydrolyized Pseudomonas aeruginosa lipopolysacharide covalently coupled to either tetanus toxoid or P. aeruginosa toxin A, utilizing a spacer molecule and a coupling agent. Conjugates produced in such a manner possess a molecular weight of greater than 350,000, are nontoxic and non-pyrogenic, and upon immunization of animals induced protective anti-LPS antibody and antibody which neutralizes the lethal effect of tetanus toxin or toxin A. The polysaccharide-tetanus toxoid conjugate and polysaccharide-toxin A conjugate are safe and immunogenic when parenterally administered to humans.
