This invention relates to peptide microarrays, methods of generating peptide microarrays, and methods of identifying peptide binders using microarrays. More specifically, this invention relates to peptide microarrays, methods of generating peptide microarrays, and methods of identifying peptide binders using microarrays wherein the microarrays comprise cyclic peptides. The invention also relates to methods and compositions for detecting the formation of cyclized peptides from linear peptides on a microarray by contacting the microarray with a detectable protein. The cyclized peptides include tags that are activated upon cyclization, facilitating the detection of successful cyclization reactions. In additional aspects, the invention relates to developing fragmented peptide tags that, upon cyclization, bind to detectable proteins. Additionally, the invention relates to methods of generating linear and cyclic peptides subarrays on a microarray.
本发明涉及肽微阵列、生成肽微阵列的方法以及使用微阵列鉴定肽结合剂的方法。更具体地说,本发明涉及肽微阵列、生成肽微阵列的方法以及使用微阵列鉴定肽结合剂的方法,其中微阵列包括环肽。本发明还涉及通过将微阵列与可检测蛋白质接触来检测微阵列上线性肽形成环化肽的方法和组合物。环化肽包括在环化时被激活的标记,有利于检测成功的环化反应。在其他方面,本发明涉及开发片段肽标签,这些标签在环化后可与可检测的蛋白质结合。此外,本发明还涉及在微阵列上生成线性和环状肽子阵列的方法。
