[edit] Carbohydrate Name

Capsular polysaccharide

[edit] Carbohydrate Class

Capsular polysaccharide

[edit] Source Microbe

Meningococci strain P355 (group B]

[edit] Basic Structure

It is a homopolymer of α(2-->8) sialic acid

[edit] 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

[edit] Antigenic Nature used to produce antibodies

Viable meningococci strain P355 (group B]

[edit] Carrier Name

nil

[edit] Conjugation Method

nil

[edit] Antibodies

Mab 2-2-B

[edit] Antibody type and class

IgM

[edit] Assay System

Quantitative precipitation analysis, Antigen-binding assay

[edit] Cross-reactivity

N/A

[edit] Proposed epitopes

N/A

[edit] 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
