PolysacDB ID1999
Carbohydrate NameDisaccharide   (Drugpedia)
Carbohydrate ClassCapsular polysaccharide
MicrobeStreptococcus pneumoniae serotype 6B   (NCBI Taxonomy)   (Drugpedia)
Basic StructureThe structure of the disaccharide is α-L-Rhap-(1-->4)-D-Rib-ol-[5-->P-->(CH2)3NH2]
BCSDB Structure5205
Proposed functionsN/A
Antigenic Nature used to produce antibodiesGlycoconjugates
Carrier NameKeyhole limpet hemocyanin
Conjugation MethodThe saccharides were coupled via the 3-aminopropyl spacer to carrier protein KLH in a stepwise reaction: the amino-terminal groups of the OS fragment and KLH were activated by S acetylation and Br acetylation, respectively, and coupled via a thioether linkage
AntibodiesAntisera
Antibody type and classN/A
Assay SystemELISA, phagocytosis assays and protection experiments
Cross-reactivityThis antisera was specific to capsular polysaccharide of strain 6B and did not cross-react with 6A strains
Proposed epitopesN/A
IEDB EpitopeN/A
Proposed UtilityThis antisera could passively protect mice against a 6B challenge
