PolysacDB ID2218
Carbohydrate NameCore oligosaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeSalmonella minnesota Re chemotype 595   (NCBI Taxonomy)   (Drugpedia)
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 Structure147530
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 MASM2
Antibody type and classIgG2b
Assay SystemEnzyme immunoassay, immunoblotting
Cross-reactivityThis Mab was specific to Re chemotype
Proposed epitopesN/A
IEDB EpitopeN/A
Proposed UtilityThis Mab would help elucidate the LPS core domain structure
Curator IDAA + AS

Assay SystemEnzyme immunoassay, ELISA
Cross-reactivityThis Mab cross-reacted with Salmoneela typhimurium SL1102 Re chemotype LPS
Proposed epitopes3-deoxy-D-mannooctulosonic acid [KDO] residues at the terminal non-reducing ends seemed to be the part of the epitope. The particular epitope was proposed to be α-Kdo [2-->4] α-Kdo [2-->6] β-D-GlcN [1-->6] α-D-GlcN [1-PO3] tetrasaccharide
IEDB EpitopeN/A
Proposed UtilityThis Mab would help elucidate the Kdo LPS domain structure
