| PolysacDB ID | 1594 |
| Carbohydrate Name | N-propionyl substituted Neisseria meningitidis group B capsular polysaccharide (Drugpedia) |
| Carbohydrate Class | Capsular polysaccharide |
| Microbe | Neisseria meningitidis Serogroup 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 | Glycoconjugates |
| Carrier Name | Tetanus toxoid |
| Conjugation Method | The oligosaccharide-protein conjugate was prepared by stirring a mixture of terminal aldehyde-containing N-Pr meningococcal B oligosaccharide with tetanus toxoid in 0.75 M potassium phosphate buffer, pH 9.0, with sodium cyanoborohydride (40 mg/ml) for 1 day at 40°C, then 2 days at ambient temperature |
| Antibodies | Mab Seam 25 |
| Antibody type and class | IgG2b |
| Assay System | ELISA, flow cytometry and indirect immunofluorescence |
| Cross-reactivity | This Mab cross-reacted with non-modified acetylaed group B capsular polysaccharide |
| Proposed epitopes | N/A |
| IEDB Epitope | N/A |
| Proposed Utility | This Mab may be useful for the identification of molecular mimetics capable of eliciting protective antibodies specific to the bacteria, without the risk of evoking autoimmune disease |
