Chromatin immunoprecipitation (ChIP) in conjunction with qPCR or next generation sequencing (ChIP-seq) is used to detect protein-DNA interaction. Typically, DNA bound to a protein of interest is captured with an antibody against this protein, and DNA is then purified from DNA-protein complexes. Here, we describe a native Chromatin immunoprecipitation (N-ChIP) approach which is an efficient ChIP method with high resolution for histone modifications and a number of transcription factors. This protocol has been tailored for cultured primary rat astrocytes, and we included the preparation of astrocytic cell cultures in this protocol.
染色质免疫沉淀(ChIP)结合定量聚合酶链反应(qPCR)或下一代测序(ChIP-seq)用于检测蛋白质与DNA的相互作用。通常,用针对目标蛋白质的抗体捕获与该蛋白质结合的DNA,然后从DNA-蛋白质复合物中纯化DNA。在此,我们描述了一种天然染色质免疫沉淀(N-ChIP)方法,它是一种高效的ChIP方法,对组蛋白修饰和许多转录因子具有高分辨率。该方案是针对原代培养的大鼠星形胶质细胞定制的,我们在本方案中纳入了星形胶质细胞培养物的制备。
