PolysacDB ID2510
Carbohydrate NameLipopolysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeVibrio cholerae 01 serogroup   (NCBI Taxonomy)   (Drugpedia)
Basic StructureIt is a linear unbranched homopolymer of 1,6-linked-D-galactopyranosyl residues.
BCSDB Structure6642
Proposed functionsV. cholerae lipopolysaccharide (LPS), a critical component of the outer membrane that is required for virulence, is a known target for immune responses following infection or immunization. Antibodies specific for V. cholerae LPS are correlated with protection against cholera
Antigenic Nature used to produce antibodiesKilled Vaccine consisting of V. cholerae O1 Inaba (ATCC 14033) and Ogawa (ATCC 14035) cells
Carrier NameNil
Conjugation MethodNil
AntibodiesMab A19
Antibody type and classIgM
Assay SystemEnzyme-linked immunosorbent assay (ELISA), immunofluorescence, Immunoelectron microscopy and the slide agglutination test
Cross-reactivityThis Mab reacted with both Inaba and Ogawa serovars (A antigen) and was specific to O1 serotype. It however reacted weakly with five V. cholerae non-O1 serovars and Serratia marcescens
Proposed epitopesThe epitope was named as Epitope A. Epitope A was postulated to be either the perosamine residues or the N-tetronic acid (N-3-deoxy-L-glycero-tetronic acid) side chain
IEDB EpitopeN/A
Proposed UtilityThe A19 anti-A antigen MAb agglutinated each O1 serovar and Serratia marcescens, albeit weakly
