[edit] Carbohydrate Name

Lipoarabinomannan

[edit] Carbohydrate Class

Miscellaneous

[edit] Source Microbe

Mycobacterium leprae

[edit] Basic Structure

Mycobacterial 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

[edit] Proposed functions

T cell proliferation and to interfere with gamma interferon-mediated activation of macrophages

[edit] Antigenic Nature used to produce antibodies

whole killed mycobacteria leprae cells

[edit] Carrier Name

nil

[edit] Conjugation Method

nil

[edit] Antibodies

Mab Cs-35

[edit] Antibody type and class

IgM

[edit] Assay System

Indirect and Competitive ELISA

[edit] Cross-reactivity

This antibody cross-reacted to M. tuberculosis and other Mycobacterium speices.

[edit] Proposed epitopes

β-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

[edit] Proposed Utility

These 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.
