fragments of the CAA glycan. To generate information on the molecular level about the glycan specificity of the relevant IgM MAbs, two series of oligosaccharides related to the CAA disaccharide epitope were synthesized, and coupled to BSA. The first three analogues, beta-D-GlcpA-(1-->3)-[small beta]-D-GlcpNAc-(1-->O), beta-D-GlcpNAc-(1-->6)-[beta-D-GlcpA-(1-->3)]-beta-D-GlcpNAc-(1-->O), and beta-D-Glcp
肠道相关循环阳极抗原(CAA)是由寄生虫曼氏血吸虫产生的主要排泄性抗原之一。CAA的免疫反应性部分是苏氨酸连接的多糖,由长段独特重复的二糖组成-> 6)-[β-D-GlcpA-(1-> 3)]-β-D-GalpNAc-(1 ->。以前,使用表面等离振子共振和ELISA技术已经显示,某些抗CAA IgM单克隆抗体(MAbs)也可以识别一系列牛血清白蛋白(BSA)偶联的合成二到五为了产生有关相关IgM MAb的聚糖特异性的分子水平信息,合成了与CAA二糖表位相关的两个系列寡糖,并与BSA偶联,前三个类似物β-D -GlcpA-(1-> 3)-[小beta] -D-GlcpNAc-(1-> O),beta-D-GlcpNAc-(1-> 6)-[beta-D-GlcpA-(1-> 3)]- beta-D-GlcpNAc-(1-> O)和beta-D-GlcpNA-(1-> 3)-beta-D-GlcpNAc-(1->
