PolysacDB ID1572
Carbohydrate NameCapsular polysaccharide   (Drugpedia)
Carbohydrate ClassCapsular polysaccharide
MicrobeNeisseria meningitidis strain P355 (group B)   (NCBI Taxonomy)   (Drugpedia)
Basic StructureIt is a homopolymer of α(2-->8) sialic acid
BCSDB StructureN/A
Proposed functionsThis 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 antibodiesViable meningococci strain P355 (group B]
Carrier NameNil
Conjugation MethodNil
AntibodiesMab 2-1-B
Antibody type and classIgM
Assay SystemQuantitative precipitation analysis, Antigen-binding assay
Cross-reactivityN/A
Proposed epitopesN/A
IEDB EpitopeN/A
Proposed UtilityThis Mab was bactericidal with human C strain and opsonized K1 polysaccharide containing E. coli in an opsonophagocytic assay with human C strain
