PolysacDB ID2486
Carbohydrate NameGlycoprotein GP72   (Drugpedia)
Carbohydrate ClassGlycoprotein
Microbe NameTrypanosoma cruzi Z2 Esmeraldo/3   (NCBI Taxonomy)   (Drugpedia)
Basic StructureGP72 is a 72-kilodalton cell surface glycoprotein found on epimastigotes and metacyclic trypomastigotes
BCSDB StructureN/A
Proposed FunctionGP72 may regulate T. cruzi morphogenesis in the insect vector
Antigenic NatureWhole cells
Carrier NameNil
Conjugate MethodNil
AntibodiesMab 8G2 B9
Antibody Type ClassIgG2a
Assay SystemELISA, immunoblotiing, indirect immunofluorescence
Cross ReactivityThis Mab cross-reacted with T. cruzi BOL Z2, and Z3 but did not react with Z1
Proposed EpitopeThis Mab binds to phosphorylated sugar side chains, which comprise 85% of GP72 carbohydrate and contain ribose, xylose, and fucose
IEDB EpitopeN/A
Proposed UtilityAnti-T. cruzi monoclonal antibodies are considered to have important applications to epidemiological studies and the improved diagnosis and prognosis of Chagas' disease
