Chromatin immunoprecipitation (ChIP) coupled with next-generation sequencing (NGS) is widely used for studying the nucleoprotein components that are involved in the various cellular processes required for shaping the bacterial nucleoid. This methodology, termed ChIP-sequencing (ChIP-seq), enables the identification of the DNA targets of DNA binding proteins across genome-wide maps. Here, we describe the steps necessary to obtain short, specific, high-quality immunoprecipitated DNA prior to DNA library construction for NGS and high-resolution ChIP-seq data.
染色质免疫沉淀（ChIP）与下一代测序（NGS）相结合，被广泛用于研究参与塑造细菌类核所需的各种细胞过程的核蛋白成分。这种方法称为ChIP测序（ChIP-seq），能够在全基因组图谱上识别DNA结合蛋白的DNA靶点。在这里，我们描述了在构建用于NGS的DNA文库和获得高分辨率ChIP-seq数据之前，获得短的、特异性的、高质量免疫沉淀DNA所需的步骤。
