Antibodies to Cryptococcus neoformans Type D have been raised in rabbits. The partially purified antibody pool was fractionated by affinity-chromatography, and it was shown that antibodies to the capsular polysaccharide of Type D were present in the pool. Neither methyl α-d-mannopyranoside, nor d-mannose were inhibitors of the binding of Type D polysaccharide to the antibody-pool. Thus it appears that the serum contains antibody populations which are specific for terminal side-chain carbohydrate moieties of the immunizing antigen.
