In this note, we demonstrate the utility of bifunctional fluorescent linkers to facilitate the construction of peptide microarrays with either an N- or a C-terminal alkylamine for directionally preferred peptide immobilization. Significantly, these small tags facilitate high-performance liquid chromatography (HPLC) profiling while limiting interference with antigen-antibody interactions after peptide immobilization. In a model peptide-antibody binding assay, a sequence-dependent orientation effect of antibody binding to a series of peptide ligands was demonstrated. This approach provides a strategy that can be applied to a variety of peptide microarray-based detection systems.
在本说明中,我们展示了双功能荧光接头的实用性,可用于构建具有 N-或 C-末端伯胺的肽微阵列,以实现定向优先肽固定。重要的是,这些小标签在限制肽固定后抗原-抗体相互作用干扰的同时,促进了高效液相色谱(HPLC)分析。在模型肽-抗体结合分析中,证明了抗体与一系列肽配体结合的序列依赖性定向效应。该方法提供了一种可应用于各种基于肽微阵列的检测系统的策略。
