A synthetic glycoarray containing non-reducing α-galactopyranosyl moieties related to mucin O-glycans of the parasite Trypanosoma cruzi was evaluated by a chemiluminescent enzyme-linked immunosorbent assay with sera from patients with chronic Chagas disease. Our data revealed the disaccharide Galα(1,3)Galβ as the immunodominant glycotope, which may eventually be employed as a diagnostic antigen for Chagas disease.
合成糖阵列含有与寄生虫克氏锥虫粘蛋白 O 聚糖相关的非还原性 α-吡喃半乳糖基部分,通过化学发光酶联免疫吸附测定对慢性恰加斯病患者的血清进行评估。我们的数据显示二糖 Galα(1,3)Galβ 作为免疫显性糖表位,最终可能用作恰加斯病的诊断抗原。
