Capture compounds and collections thereof and methods using the compounds for the analysis of biomolecules are provided. In particular, collections, compounds and methods are provided for analyzing complex protein mixtures, such as the proteome. The compounds are multifunctional reagents that provide for the separation and isolation of complex protein mixtures. Each compound has the formula:
wherein: Z is a trityl derivative; X, the reactivity function, covalently binds to amino acid side chains of proteins; Y, the selectivity function, modulates binding of X to the amino acid side chains in proteins such that X binds to fewer proteins when Y is present than in its absence; and Q permits separation or immobilization of the capture compound. Automated systems for performing the methods also are provided.
本文提供了捕获化合物和化合物集合以及使用这些化合物进行生物分子分析的方法。特别地,提供了用于分析复杂蛋白质混合物(如蛋白质组)的集合、化合物和方法。这些化合物是多功能试剂,可用于分离和分离复杂蛋白质混合物。每个化合物的公式为:其中:Z是三苯甲基衍生物;X是反应性功能,共价结合到蛋白质的氨基酸侧链上;Y是选择性功能,调节X与蛋白质中氨基酸侧链的结合,使得在Y存在时,X与较少的蛋白质结合,而在Y不存在时,X与更多的蛋白质结合;Q允许分离或固定捕获化合物。本文还提供了用于执行这些方法的自动化系统。
