Monoclonal antibody EBCA-1 is used in the sandwich immune assay for the detection of circulating mannan in blood sera samples for the diagnosis of invasive candidiasis. To reinvestigate carbohydrate specificity of EBCA-1, a panel of biotinylated oligosaccharides structurally related to distinct fragments of mannan were loaded onto a streptavidin-coated plate to form a glycoarray. Its use demonstrated that EBCA-1 recognizes the trisaccharide β-Man-(1→2)-α-Man-(1→2)-α-Man and not homo-α-(1→2)-linked pentamannoside, as was reported previously.
单克隆抗体EBCA-1用于夹心免疫测定,以检测血清样本中的循环甘露聚糖,用于侵袭性念珠菌病的诊断。为了重新研究EBCA-1的碳水化合物特异性,将一组与甘露聚糖不同片段结构相关的生物素化寡糖加载到链霉亲和素包被的板上以形成糖阵列。其应用表明,EBCA-1识别三糖β-Man-(1→2)-α-Man-(1→2)-α-Man,而不像先前报道的那样识别同型α-(1→2)连接的五甘露糖苷。
