PolysacDB ID1457
Carbohydrate NameLipopolysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeHaemophilus influenzae RM.7004   (NCBI Taxonomy)   (Drugpedia)
Basic StructureIt consists of an oligosaccharide linked via a 3-deoxy-D-manno-octulosonic acid (Kdo) residue to a lipid A region. The core is often divided into two regions: an inner core consisting of a heptose (Hep) and a Kdo residue and an outer core containing galactose (Gal) and glucose (Glc)
BCSDB StructureN/A
Proposed functionsLPS plays an important role in the infection process
Antigenic Nature used to produce antibodiesAzide-killed H. influenzae RM.7004
Carrier NameNil
Conjugation MethodNil
AntibodiesMab MAHI 3
Antibody type and classIgG2b
Assay SystemEnzyme immunoassay, colony dot immunoblotting, and immunoblotting
Cross-reactivityMAHI 3 bound to all H. influenzae, all other human Haemophilus spp., all Bordetella pertussis and Bordetella parapertussis, and all Aeromonas spp. tested but not to any Neisseria or Moraxella catarrhalis strains
Proposed epitopesThe structural element recognized by MAHI 3 is Hepα1-->2Hepα1-->3Hepα1-->Kdo together with part of lipid A, including the phosphate
IEDB EpitopeN/A
Proposed UtilityThis Mab would help to detect the organism in environmental samples and clinical specimens
