PolysacDB ID1631
Carbohydrate NameLipoarabinomannan-B   (Drugpedia)
Carbohydrate ClassGlycolipid
Microbe NameMycobacterium 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 StructureN/A
Proposed FunctionT cell proliferation and to interfere with gamma interferon-mediated activation of macrophages
Antigenic NatureSoluble extract of M. leprae
Carrier NameNil
Conjugate MethodNil
AntibodiesMab SAl.C7F
Antibody Type ClassIgG1
Assay SystemAntigen capture ELISA, direct binding assay,
Cross ReactivityThis Mab was specific to M. leprae and did not cross-react with lipoarabinomannan from M. tuberculosis
Proposed EpitopeN/A
IEDB EpitopeN/A
Proposed UtilityThis Mab becomes applicable for monitoring several individual M . Leprae antigens such as lipoarabinomannan
Curator IDAA + AS
Date of Curation25-09-2010
References2467001
