PolysacDB ID1497
Carbohydrate NameCapsular polysaccharide   (Drugpedia)
Carbohydrate ClassCapsular polysaccharide
MicrobeCryptococcus neoformans Serotype A [strain 24064]   (NCBI Taxonomy)   (Drugpedia)
Basic StructureThe major component of C. neoformans capsular polysaccharide is glucurunoxylomannan [GXM] consisting of an unbranched mannose backbone substituted with xylose, glucuronic acid and O-acetyl residues
BCSDB StructureN/A
Proposed functionsThe major component of C. neoformans capsular polysaccharide is glucurunoxylomannan [GXM] consisting of an unbranched mannose backbone substituted with xylose, glucuronic acid and O-acetyl residues
Antigenic Nature used to produce antibodiesWhole cells
Carrier NameNil
Conjugation MethodNil
AntibodiesMab 5E9
Antibody type and classIgM
Assay SystemELISA
Cross-reactivityThis antibody reacted with 2 serotype A strains 24064 and 371
Proposed epitopesMab 5E9 bound to de-O-acetylated GXM of strain 371 but not of strain 24064. This shows the probable epitope to be variable among strains and to be acetylation independent
