| PolysacDB ID | 2462 |
| Carbohydrate Name | 6B polysaccharide [octavalent polysaccharide protein conjugate vaccine, PncT] (Drugpedia) |
| Carbohydrate Class | Capsular polysaccharide |
| Microbe | Streptococcus pneumoniae serogroup 6 (NCBI Taxonomy) (Drugpedia) |
| Basic Structure | N/A |
| BCSDB Structure | N/A |
| Proposed functions | N/A |
| Antigenic Nature used to produce antibodies | Glycoconjugate |
| Carrier Name | Nil |
| Conjugation Method | Nil |
| Antibodies | Human Antisera |
| Antibody type and class | IgG |
| Assay System | ELISA, Opsonophagocytosis assay, in-vivo protection assay |
| Cross-reactivity | This antisera cross-reacts with serotype 6A |
| Proposed epitopes | N/A |
| IEDB Epitope | N/A |
| Proposed Utility | This antisera protected mice against bacteremia and/or lung infection caused by intranasal challenge with serotypes 6B and 6A |
| Curator ID | AA + AS |
| Date of Curation | 24-05-2011 |
| References | 11110649 |
| PolysacDB ID | 2466 |
| Carbohydrate Name | Pneumococcal vaccine PP (Drugpedia) |
| Carbohydrate Class | Lipopolysaccharide |
| Microbe | Streptococcus pneumoniae (NCBI Taxonomy) (Drugpedia) |
| Basic Structure | This vaccine includes the polysaccharides of 6B, 14, 19F, 18C, 23F serotypes |
| BCSDB Structure | N/A |
| Proposed functions | N/A |
| Antigenic Nature used to produce antibodies | Glycoconjugates |
| Carrier Name | Diphtheria toxin mutant (CRM197) |
| Conjugation Method | The oligosaccharide-CRM197 conjugates were synthesized by either first hydrolysing the native oligosaccharide [PS] to smaller fragments and then subjecting the fragments to limited periodate oxidation or by oxidizing the native PS and then hydrolyzing it into smaller fragments. The PS-CRM197 conjugates were synthesized by oxidizing native pneumococcal PS with sodium metaperiodate to introduce random aldehyde functional groups. Oxidized OS or PS fragments were coupled to CRM197 in the presence of sodium cyanoborohydride |
| Antibodies | Human Antisera |
| Antibody type and class | N/A |
| Assay System | ELISA, Opsonophagocytic killing assay |
| Cross-reactivity | The antisera reacted with 6B serotype, showed good opsonophagocytic activity for 19F serotype. This antisera also cross-reacted with 6A serotype but did not react with 19A serotype |
| Proposed epitopes | N/A |
| IEDB Epitope | N/A |
| Proposed Utility | The findings suggest that some conjugate vaccines may elicit cross-protection against related polysaccharides better than others |
