染色质免疫沉淀 (ChIP) 广泛应用于许多领域,用于分析特定蛋白质或其修饰亚型在定义的 DNA 结构域中的分布。 ChIP 程序分为两大类,即使用通过核酸酶消化制备的天然染色质的程序(称为 NChIP),以及使用 DNA 和蛋白质通过化学或紫外线交联的染色质的程序(称为 XChIP)。每个程序都有其自身的优点和缺点。在这里,我们概述了我们实验室目前使用的从培养细胞中分离和免疫沉淀天然染色质,以及分离和分析免疫沉淀的蛋白质和 DNA 的方法。 (C) 2003 年爱思唯尔科学(美国)。版权所有。
Chromatin immunoprecipitation (ChIP) is widely used in many fields to analyze the distribution of specific proteins, or their modified isoforms, across defined DNA domains. ChIP procedures fall into two main categories, namely, those that use native chromatin prepared by nuclease digestion (designated NChIP), and those that use chromatin in which DNA and proteins are crosslinked, either chemically or with UV light (designated XChIP). Each procedure has its own advantages and drawbacks. Here, we outline the methods currently in use in our laboratory to isolate and immunoprecipitate native chromatin from cultured cells, and to isolate and analyze immunoprecipitated protein and DNA.
