Basic StructureO-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

Assay SystemELISA
Cross-reactivityThis Mab was specific to A and M strains of Brucella and did not cross-react with S-LPSs of S. urbana, Vibrio cholerae and E. coli O:157 but bound better to M-dominant S-LPS than to A-dominant S-LPS
Proposed epitopesThis Mab was specific to the C epitope
IEDB EpitopeN/A
Proposed UtilityThis Mab helped in the epitope strucure elucidation
