Synthetically prepared ribosylribitol phosphate dimer and trimer analogous to fragments of the capsular polysaccharide of Haemophilus influenzae type b, containing either an amino- or a (masked) thiol-functionalized spacer, were conjugated to protein by two different methods. The thiol-containing carbohydrates were conjugated to tetanus toxoid or H. influenzae outer membrane protein using N-succinimidyl 3-(2-pyridyldithio)propionate. Glutaric dialdehyde was used to conjugate the amino-containing carbohydrates with tetanus toxoid. All conjugates were able to bind antibodies raised against the native bacterial polysaccharide, as determined by competition ELISA. The glutaric dialdehyde conjugate prepared from ribosylribitol phosphate trimer and tetanus toxoid induced a strong polysaccharide-specific antibody response in mice and rabbits.
