of proteins based on their binding patterns. Microarrays displaying 5035 unique binding environments were prepared using a library of 19 small molecule building blocks. Each building block was equipped with a carboxylic acid handle, allowing mixtures of the building blocks to be spotted onto the surface of an amine functionalized glass slide for covalent immobilization as subunits of the binding environments
本文介绍了组合人工受体阵列 (CARA) 的构建以及该阵列在基于其结合模式的蛋白质分化中的应用。显示 5035 个独特结合环境的微阵列是使用 19 个小分子构建块的库制备的。每个构建块都配备了一个羧酸手柄,允许构建块的混合物被点在胺官能化的载玻片的表面上,以作为结合环境的亚基进行共价固定。该策略采用微阵列表面作为受体合成平台,从而实现阵列制备的灵活性和应用的敏捷性。CARA 策略的一个优势是它在构建替代微阵列配置方面具有巨大的灵活性,这有助于快速访问绑定空间的广度和深度。四种荧光标记的蛋白质、泛素、肌红蛋白、α-1-酸性糖蛋白和溶菌酶与阵列一起孵育,以证明结合的重现性和可以实现的分化水平。绑定环境稳定、可扩展,并适用于其他格式。
