PolysacDB ID1579
Carbohydrate NameN-propionyl substituted Neisseria meningitidis group B capsular polysaccharide    (Drugpedia)
Carbohydrate ClassCapsular polysaccharide
Microbe NameNeisseria meningitidis Serogroup B   (NCBI Taxonomy)   (Drugpedia)
Basic StructureIt is a homopolymer of α(2-->8) sialic acid
BCSDB StructureN/A
Proposed FunctionThis 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 NatureGlycoconjugates
Carrier NameTetanus toxoid
Conjugate MethodThe 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
AntibodiesMab Seam 10
Antibody Type ClassIgG1
Assay SystemELISA, flow cytometry and indirect immunofluorescence
Cross ReactivityThis Mab cross-reacted with non-modified acetylaed group B capsular polysaccharide
Proposed EpitopeN/A
IEDB EpitopeN/A
Proposed UtilityThis 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

Proposed FunctionThis 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 NatureGlycoconjugates
Carrier NameTetanus toxoid
Conjugate MethodThe 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
AntibodiesMab Seam 29
Antibody Type ClassIgG2a
Assay SystemELISA, flow cytometry and indirect immunofluorescence
Cross ReactivityThis Mab cross-reacted with non-modified acetylaed group B capsular polysaccharide. This Mab also cross-reacted with polysialic acid on CHP-134 neuroblastoma cells
Proposed EpitopeN/A
IEDB EpitopeN/A
Proposed UtilityThis 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
