[edit] Carbohydrate Name

O-polysaccharide

[edit] Carbohydrate Class

O-polysaccharide [LPS]

[edit] Source Microbe

Brucella melitensis 16M

[edit] Basic Structure

O-polysaccharide is a homopolymer of 4,6-dideoxy-4-formamidoct-D-mannopyranose residues

[edit] Proposed functions

N/A

[edit] Antigenic Nature used to produce antibodies

B.melitensis 16M formaldehyde-killed cells

[edit] Carrier Name

nil

[edit] Conjugation Method

nil

[edit] Antibodies

Mab BM2-28

[edit] Antibody type and class

IgG3

[edit] Assay System

ELISA, immunodiffusion and competitive inhibition assay

[edit] Cross-reactivity

This antibody was specific to B. melitiensis and did not cross-reac with O-polysaccharide of B. abortus and Yersinia enterocolitica O:9 polysaccharide

[edit] Proposed epitopes

This Mab reacted only with M antigen. The crucial element of the M epitope is a disaccharide, α-D-Rha4NFo(1-->3)α-D Rha4NFo, that requires adjacent α1,2-linked residues for full activity. The common epitope of A and M antigens is a linear α1,2-linked tri or tetrasaccharide

[edit] Proposed Utility

This Mab can be used as a use as standard Brucella typing or detection reagents
