CarboDB Galactomannan 1130
From DrugPedia: A Wikipedia for Drug discovery
[edit] Carbohydrate Name
Galactomannan
[edit] Carbohydrate Class
Miscellaneous
[edit] Source Microbe
Aspergillus flavus EV 601
[edit] Basic Structure
Galactomannans are composed of an α-1,6-linked mannan backbone substituted with mannopyranose oligosaccharides and immunodominant terminal galactofuranose present either singly or linked to oligogalactosides
[edit] Proposed functions
The wide distribution and similar chemical structure of the galactomannans have been responsible for serologic cross-reactions
[edit] Antigenic Nature used to produce antibodies
A mycelial extract of A. fumigatus EV 601
[edit] Carrier Name
nil
[edit] Conjugation Method
nil
[edit] Antibodies
Mab EBA-2
[edit] Antibody type and class
IgM
[edit] Assay System
ELISA, Immunofluorescence and immunoblotting
[edit] Cross-reactivity
This Mab cross-reacted with the five Aspergillus species (A. fumigatus ATCC 1028, A. flavus ATCC 10124, A. niger ATCC 10549, A. versicolor ATCC 16845, and A. terreus CBS 106.25) but not with other medically important fungi, such as Sporothrix schenckii ATCC 14096 and Candida spp. (25 strains, including 10 ATCC strains, 2 CBS strains, and 13 clinical isolates, representing seven species, i.e., C. albicans, C. tropicalis, C. [Torulopsis] glabrata, C. pseudotropicalis, C. parapsilosis, C. guilliennondii, and C. krusei). They also failed to react with the 15 different bacterial species tested
[edit] Proposed epitopes
an epitope located on the β(1-->5) galactofuranose containing side chains of the galactomannan molecule
[edit] Proposed Utility
EB-A2 has been used to detect circulating antigen in the serum of patients with invasive aspergillosis by ELISA inhibition
