Carbohydrate Name

O-polysaccharide

Carbohydrate Class

O-polysaccharide [LPS]

Source Microbe

Brucella abortus W99

Basic Structure

O-polysaccharide consists of an unbranched linear homopolymer of 10 to 100 α-1,2-linked 4-formamido-4,6-dideoxy-D-mannose (N formylperosamine) residues. The O-polysaccharide is covalently linked to a core oligosaccharide

Proposed functions

N/A

Antigenic Nature used to produce antibodies

Whole B. abortus W99 cells

Carrier Name

nil

Conjugation Method

nil

Antibodies

Mab 4F9

Antibody type and class

IgG3

Assay System

ELISA

Cross-reactivity

This antibody did not cross-react with S-LPSs of S. urbana, Vibrio cholerae and E. coli O:157, but cross-reacted with S-LPS of Y. enterocolitica O:9 along with Brucella A and M dominant strains. Reactivity was more towards A dominant strains

Proposed epitopes

This Mab was directed against the C/Y epitope and did not consist of α1,2-linked D-Rha4NFo residues. This Mab did not bind purified O-polysaccharide

Proposed Utility

This Mab helped in the epitope strucure elucidation
