| pubmed-article:9090720 | pubmed:abstractText | Two lipophosphoglycans (LPG) from two Leishmania mexicana (Soberano and Yucatan) strains, isolated in Mexico, were purified by affinity chromatography with the Con A lectin. The LPG from each strain, with a 10 kDa molecular weight, possesses two fractions: one with high mannose concentrations and the other with a more heterogeneous saccharidic composition; the mannose-rich fraction and the heterogeneous fraction from the Yucatan strain show a single band of identity with rabbit IgG against promastigotes from L. mexicana Yucatan. Antigen recognition was abolished by treating the high mannose LPGs with alpha-mannosidase. The presence of non reductor alpha-mannose sequences, as determinant epitopes in L. mexicana Soberano and Yucatan strains, was determined by mass spectrometry analysis and enzymatic cleavage. | lld:pubmed |
