PolysacDB ID1576
Carbohydrate NameMeningococcal polysaccharide group B   (Drugpedia)
Carbohydrate ClassCapsular polysaccharide
Microbe NameNeisseria meningitidis B (CN7783)   (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 NatureWhole cells
Carrier NameNil
Conjugate MethodNil
AntibodiesMab MB-32
Antibody Type ClassIgM
Assay SystemRadioimmunoassay, counter immunoelectrophoresis and agglutination
Cross ReactivityN/A
Proposed EpitopeN/A
IEDB EpitopeN/A
Proposed UtilityThis Mab conferred very weak passive protection of mice infected with either Neisseria meningitidis group B or Escherichia coli K 1
Curator IDAA + AS
