PolysacDB ID1015
Carbohydrate NameBeta-glucan   (Drugpedia)
Carbohydrate ClassCapsular polysaccharide
MicrobeCandida albicans   (NCBI Taxonomy)   (Drugpedia)
Basic StructureGlucans are a heterogeneous group of glucose polymers, consisting of a backbone of β(1-->3)-linked β-D-glucopyranosyl units with β(1-->6)-linked side chains of varying distribution and length
BCSDB Structure125281
Proposed functionsGlucan is an essential cell wall component in pathogenic fungi and plays a critical role in cell viability
Antigenic Nature used to produce antibodiesGlycoconjugates
Carrier NameDiphtheria toxoid CRM 197
Conjugation MethodA 20-fold molar excess of activated polysaccharide was reacted overnight with the protein, at room temperature, in 10 mM phosphate buffer, pH 7.2. The unbound polysaccharide was separated from the glyco-conjugate by ultrafiltration, using Amicon 10-kD filter devices
AntibodiesPolysera
Antibody type and classIgG
Assay SystemInvivo protection assays, growth inhibition assays, indirect ELISA
Cross-reactivityN/A
Proposed epitopesN\A
IEDB Epitope76671
Proposed UtilityThe Lam-CRM conjugate is immunogenic and protective against systemic candidiasis in mice. The antibodies induce passive protection in mice against systemic and mucosal candidiasis
