PolysacDB ID2636
Carbohydrate NameGlucurunoxylomannan   (Drugpedia)
Carbohydrate ClassCapsular polysaccharide
MicrobeCryptococcus neoformans Serotype A   (NCBI Taxonomy)   (Drugpedia)
Basic StructureA linear α(1-->3)- linked mannan backbone singly substituted with non-reducing β(1-->2) xylose and β(1-->2) glucuronic acid side branches ; O-acetyl groups are present at C-6 of the mannosyl residues
BCSDB Structure116826
Proposed functionsAntiphagocytic ; an important virulence factor
Antigenic Nature used to produce antibodiesGlycoconjugates
Carrier NameTetanus toxoid
Conjugation MethodConjugated using CDAP chemistry
AntibodiesMab 13F1
Antibody type and classIgM
Assay SystemELISA
Cross-reactivityThis antibody cross-reacted with Serotype A,B,C and D serotypes
Proposed epitopesThis Mab did not bind de-O-acetylated GXM suggesting that acetylated residues form an important part of the epitope
IEDB Epitope115576
Proposed UtilityThis antibody was used to decipher and differentiate the serum antibody response of autoimmune mice as compared to normal mice
