| PolysacDB ID | 1070 |
| Carbohydrate Name | Capsular polysaccharide (Drugpedia) |
| Carbohydrate Class | Capsular polysaccharide |
| Microbe | Neisseria meningitidis Serogroup B (NCBI Taxonomy) (Drugpedia) |
| Basic Structure | The capsular polysaccharide, also known as K-antigen consists of repeating units of following residues : -8)α-Neup5Ac(2- [a homopolymer of α(2-->8) sialic acid residues] |
| BCSDB Structure | 139710 |
| Proposed functions | N/A |
| Antigenic Nature used to produce antibodies | Live group B type 15 meningococci cells |
| Carrier Name | Nil |
| Conjugation Method | Nil |
| Antibodies | Mab 2-2-B |
| Antibody type and class | IgM |
| Assay System | ELISA and Radioimmunoassay |
| Cross-reactivity | This antibody cross-reacted with E. coli strain K1 Capsular polysaccharide |
| Proposed epitopes | N/A |
| IEDB Epitope | N/A |
| Proposed Utility | This Mab provided protection against the E. coli K-1 strain |
| Curator ID | AA + AS |
| Date of Curation | 21-01-2010 |
| References | PMC261141 |
| PolysacDB ID | 1573 |
| Carbohydrate Name | Capsular polysaccharide (Drugpedia) |
| Carbohydrate Class | Capsular polysaccharide |
| Microbe | Neisseria meningitidis strain P355 (group B) (NCBI Taxonomy) (Drugpedia) |
| Basic Structure | It is a homopolymer of α(2-->8) sialic acid |
| BCSDB Structure | N/A |
| Proposed functions | This capsular polysaccharide is an important virulence determinant. Serum antibodies to the group B polysaccharide confers protection against disease by activating complement-mediated bacteriolysis and/or opsonization. It leads to immunologic tolerance induced by prenatal exposure to host polysialyated glycoproteins |
| Antigenic Nature used to produce antibodies | Viable meningococci strain P355 (group B] |
| Carrier Name | Nil |
| Conjugation Method | Nil |
| Antibodies | Mab 2-2-B |
| Antibody type and class | IgM |
| Assay System | Quantitative precipitation analysis, Antigen-binding assay |
| Cross-reactivity | N/A |
| Proposed epitopes | N/A |
| IEDB Epitope | N/A |
| Proposed Utility | This Mab was bactericidal with human C strain and opsonized K1 polysaccharide containing E. coli in an opsonophagocytic assay with human C strain |
