PolysacDB ID1178
Carbohydrate NameLipoologosaccharide band B of the LPS   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
Microbe NameBordetella pertusis 134 LOS B variant strain   (NCBI Taxonomy)   (Drugpedia)
Basic StructureB. pertusis LPS is resolved electrophoretically into two bands, a slowly migrating band designated LOS A and a fast-migrating band designated LOS B. These two species differ in molecular weight as three N-acetyl amino sugars found on LOS A are not present on LOS B
BCSDB StructureN/A
Proposed FunctionThe LOS of B. pertussis exhibits biological activities similar to those of endotoxins from other gram-negative bacteria, including pyrogenicity, toxicity, induction of the Shwartzman reaction, induction of tumor necrosis factor production, and adjuvant properties
Antigenic NatureN-Lauroyl sarcosine membrane extract (SME) from B. pertussis 9340
Carrier NameNil
Conjugate MethodNil
AntibodiesMab BL-8
Antibody Type ClassIgM
Assay SystemAntibody accessibility radioimmunobinding assay, Immunoblotting
Cross ReactivityThis Mab reacted with all B. pertussis and Bordetella bronchiseptica Vir- (avirulent) variant strains tested but is not present on Bordetella parapertussis and B. bronchiseptica Vir+ (virulent) wild-type strains
Proposed EpitopeN/A
IEDB EpitopeN/A
Proposed UtilityModerate lytic activity against a mutant strain expressing only the LOS B band was observed with this Mab
