Glycolipids cluster in plasma membranes to form heterogenous patches. Whereas lectins and antibodies have been conventionally viewed as binding a single oligosaccharide head group, and assayed accordingly, it is increasingly evident that cis-interactions between glycan headgroups may form unique molecular shapes that either enhance or attenuate binding of antibodies and other proteins. Herein we describe a method for assaying antibody binding to heteromeric glycolipid complexes that allows rapid, simple, inexpensive and high-throughput assessment of binding events, focusing on autoantibodies present in human serum.
糖脂在质膜中聚集形成异质斑块。虽然凝集素和抗体传统上被视为结合单个寡糖头部基团,并据此进行检测,但越来越明显的是,聚糖头部基团之间的顺式相互作用可能形成独特的分子形状,从而增强或减弱抗体和其他蛋白质的结合。在此,我们描述了一种检测抗体与异聚糖脂复合物结合的方法,该方法能够快速、简单、廉价且高通量地评估结合事件,重点关注人血清中存在的自身抗体。
