[edit] Carbohydrate Name

Galactomannan

[edit] Carbohydrate Class

Miscellaneous

[edit] Source Microbe

Aspergillus fumigatus

[edit] Basic Structure

Galactomannan is composed of a branched core containing α(1-->2)- and α(1-->6)-linked mannose, with β(1-->5)galactofuranose and/or β(1-->4)galactopyranose moieties linked linearly in side chains terminated by galactofuranose nonreducing end units

[edit] Proposed functions

Galactomannan is a major cell wall component in Aspergillusspecies and can also be secreted into the medium as a component of the exoantigen. The galactomannan is immunogenic and polyclonal antibodies against it have been used in antigen detection for the diagnosis of invasive aspergillosis, and in the detection of fungal contamination in foodstuffs

[edit] Cross-reactivity

This antibody was cross-reactive with C.albicans

[edit] Proposed epitopes

Mannopyranosyl side chain

[edit] Proposed Utility

This antibody can be used to detect circulating antigen in the serum of patients with invasive aspergillosis by ELISA inhibition.
