PolysacDB ID1671
Carbohydrate NameGlycopeptidolipid antigen   (Drugpedia)
Carbohydrate ClassGlycolipid
MicrobeMycobacterium avium complex serovar 8   (NCBI Taxonomy)   (Drugpedia)
Basic StructureThis antigen is composed of a glycosylated lipopeptide core, fatty acyl-D-phenylalanine-D-allothreonine-D-alanine-L-alaninyl-O-(3,4-di-O-methyl-α-L-rhamnopyranoside), to which a haptenic oligosaccharide is linked at the threonine substituent
BCSDB Structure109375
Proposed functionsThis oligosaccharide unit is the source of the dominant immunogenicity of members of the M. avium complex, i.e., their characteristic agglutinability and type specificity
Antigenic Nature used to produce antibodiesWhole cells combined with whole unfractionated lipid
Carrier NameNil
Conjugation MethodNil
AntibodiesMab 5F7
Antibody type and classIgG3
Assay SystemELISA, Inhibition assays, dot blot
Cross-reactivityThis antibody cross-reacted with whole cells of serovar 8, acetylated-GPL-8, and GPL-8
Proposed epitopes4,6-(l'-carboxyethylidene)-3-0-methyl-beta-D-glucopyranosyl residues seemed to be a part of the epitope
IEDB Epitope76853
Proposed UtilityThis Mab can be used for the identification and classification of M. avium isolates. This Mab can be applied directly to bacterial cultures, thus allowing easy, rapid identification of at least half of the M. avium isolates encountered in the clinical laboratory
