Carbohydrate NameLipoarabinomannan   (Drugpedia)
Carbohydrate ClassGlycolipid
MicrobeMycobacterium leprae   (NCBI Taxonomy)   (Drugpedia)
Basic StructureMycobacterial lipoarabinomannan is a phosphatidylinositol anchored lipoglycan that consists of an α1-->6 linked backbone, substituted to varying degrees at position 2 with single α-Man residues and directly attached to position 6 of the myo-inositol of a phosphatidylinositol (PI) anchor
BCSDB Structure127448
Proposed functionsT cell proliferation and to interfere with gamma interferon-mediated activation of macrophages
Antigenic Nature used to produce antibodiesWhole killed mycobacteria leprae cells
Carrier NameNil
Conjugation MethodNil
AntibodiesMab Cs-35
Antibody type and classIgM
Assay SystemIndirect and Competitive ELISA
Cross-reactivityThis antibody cross-reacted to M. tuberculosis and other Mycobacterium speices.
Proposed epitopesβ-D-Araf- (1-->2)-α-D-Araf-(1-->5)-α- D-Araf-(1-->5)-α-D-Araf within the branched hexa-Araf motif of mycobacterial arabinans
IEDB Epitope76797
Proposed UtilityThese antibodies could be used for screening of cell-wall mutants of mycobacteria lacking AG and AraLAM motifs and the recognition of biosynthetic intermediates of cell-wall polysaccharides unique to mycobacteria.
