[A carbohydrate-containing copolymer with the specificity of a capsular polysaccharide of type 3 Streptococcus pneumoniae].

The synthesis of allyl beta-glycoside of cellobiuronic acid by chemical modification of cellobiose was described. The carbohydrate-containing polymers with different content of determinant groups were obtained via radical copolymerization of this hapten with acrylamide. The copolymer which contained 27% carbohydrates and had molecular mass about 100-300 kilodaltons had the serological specificity of the capsular polysaccharide Streptococcus pneumoniae type 3 as shown by an enzyme linked immunosorbent assay.
