PolysacDB ID1571
Carbohydrate NameLipopolysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeLeptospira interrogans serovar pomona   (NCBI Taxonomy)   (Drugpedia)
Basic StructureThe oligosaccharide contained rhamnose, ribose, glucose, and glucosamine
BCSDB StructureN/A
Proposed functionsN/A
Antigenic Nature used to produce antibodiesGlycoconjugates
Carrier NameDiphtheria toxoid
Conjugation MethodThe oligosaccharide was modified as follows : it was dissolved in N-ethylmorpholine-water-12 N HCl (2.5:6.5:1 [vol/vol/vol], pH 8.5) in concentrations of approximately 24 umol in 250ul. 125umol of N-succinimidyl S-acetylmercaptoacetate in 250ul of N,N dimethylacetamide was added to the oligosaccharide. This solution was added to modified diphtheria toxoid
AntibodiesPolysera
Antibody type and classIgG and IgM
Assay SystemEnzyme Immunoassay, immunoblotting and dot blot
Cross-reactivityThis antisera cross-reacted with LPS from some other leptospiral serovars (serovars hardjobovis, ballum, copenhageni, canicola, grippotyphosa, and batavia) and LPS from other bacteria (Salmonella typhimurium and the Re mutant of Shigella flexneri) and did not react with serovars australis, grippotyphosa, ballum, or tarassovi
Proposed epitopesN/A
IEDB EpitopeN/A
Proposed UtilityThis antiserum induced a high CL response in mouse macrophage monolayers
