SYNTHESIS AND STUDY OF ANTI-TUMOR VACCINES
… We hypothesized that conjugation of an L-rhamnose (Rha) moiety to a carbohydrate antigen would increase the immune response against the antigen in mice possessing anti-Rha antibodies via an antibody-dependent antigen uptake mechanism. To explore this hypothesis we synthesized a …
