Basic StructureLPS is a complex macromolecule composed of the biologically active lipid A moiety, covalently attached core oligosaccharide, and distally linked polysaccharide O-side chain. The core oligosaccharide part consists of the following residues : α-Kdop-(2-8)-α-Kdop-(2-->4)-Kdo
BCSDB StructureN/A
Proposed functionsLPS plays an important virulence role based on its antiphagocytic and endotoxic properties
Antigenic Nature used to produce antibodiesWhole cells
Carrier NameNil
Conjugation MethodNil
AntibodiesMab E1
Antibody type and classIgG3
Assay SystemDirect and inhibition enzyme immunoassays
Cross-reactivityMAb E1 reacted exclusively with those of Re-chemotype
Proposed epitopesIt recognized α-Kdo- monosaccharide and disaccharide structures present as non-reducing side chains in various Re-type LPSs and synthetic antigens
IEDB EpitopeN/A
Proposed UtilityThis Mab can be used for identification of Salmonella strains having the Re chemotype
