| PolysacDB ID | 2409 |
| Carbohydrate Name | Group B antigen (Drugpedia) |
| Carbohydrate Class | Capsular polysaccharide |
| Microbe | Streptococcus Group B strain M732 (NCBI Taxonomy) (Drugpedia) |
| Basic Structure | This polysaccharide had a molecular size > 5 x 106. Its main chemical constituents were sialic acid (24%), galactose (25%), a sugar tentatively identified as heptose (21%), glucose (13%), glucosamine (10%) and mannose (7%)

| BCSDB Structure | N/A |
| Proposed functions | N/A |
| Antigenic Nature used to produce antibodies | Formalin-killed whole cell vaccines |
| Carrier Name | Nil |
| Conjugation Method | Nil |
| Antibodies | Antisera |
| Antibody type and class | N/A |
| Assay System | Capillary precipitin tests, immunodiffusion tests, immunoelectrophoresis |
| Cross-reactivity | This antisera cross-reacted with the TCA antigenas well as the EDTA-non pH titrated antigen and the group B antigen extracted with formamide from strain 090R or D136C |
| Proposed epitopes | L-rhamnose was the immunodominant sugar for the formamide-extracted B antigen |
| IEDB Epitope | N/A |
| Proposed Utility | This antisera has helped determine that two antigens that react identically with each other and with similar specificities of antibody, yet with different immunodominant determinants |
