[Abstract]  Chromatin Immunoprecipitation coupled either to qPCR (qChIP) or high-throughput sequencing (ChIP-Seq) has been extensively used in the last decades to identify the DNA binding sites of transcription factors or the localization of various histone marks along the genome. The ChIP experiment generally includes 7 steps: collection of biological samples (A), cross-linking proteins to DNA (B), chromatin isolation and fragmentation by sonication (C), sonication test (D), immunoprecipitation with antibodies against the protein or the histone mark of interest (E), DNA recovery (E), identification of factor-associated DNA sequences by PCR or sequencing (F). The protocol described here can readily be used for ChIP-seq and ChIP-qPCR experiments. The entire procedure, describing experimental setup ... [摘要]  与qPCR(qChIP)或高通量测序(ChIP-Seq)相结合的染色质免疫沉淀已被广泛用于识别转录因子的DNA结合位点或基因组中各种组蛋白标记的定位。 ChIP实验通常包括7个步骤:收集生物样品(A),交联蛋白质到DNA(B),染色质分离和通过超声处理分离(C),超声处理测试(D),用针对蛋白质的抗体进行免疫沉淀感兴趣的组蛋白标记(E),DNA回收(E),通过PCR或测序鉴定因子相关DNA序列(F)。这里描述的协议可以容易地用于ChIP-seq和ChIP-qPCR实验。描述在完整的果蝇组织中优化分析的实验设置条件的整个过程可以在四天内完成。

背景 尽管永生化的培养细胞广泛用于研究各种细胞类型的染色质景观,但是在生理条件下在体内探测相互作用的有价值的方法对于进行转录的时间或空间比较分析是必要的因子和组蛋白修饰图在不同阶段的果蝇发展或不同组织之间。在这里,我们提供了一个详细的ChIP协议,已被优化,以便在整个果蝇胚胎和幼虫成像光盘上工作,突出关键的实验参数。

[Abstract]  The establishment of a cell culture system for hepatitis C virus based on the JFH-1 strain and human hepatoma cell lines has been instrumental for the study of the viral replication cycle. The robustness of the JFH1-based cell culture models enabled many laboratories around the world to perform HCV infections in cell culture, accelerating the identification of cellular and viral targets to develop novel antiviral compounds. Although other robust infection systems based on different molecular clones and different cell lines have been developed since then, here we describe the protocols corresponding to infections with JFH-1 and JFH1-derived viruses carried out in our laboratory to produce virus stocks and persistently infected cell cultures. We also describe the experimental setups used to ... [摘要]  基于JFH-1毒株和人肝癌细胞系的丙型肝炎病毒的细胞培养系统的建立已经有助于研究病毒复制周期。 基于JFH1的细胞培养模型的鲁棒性使世界上许多实验室在细胞培养物中执行HCV感染,加速细胞和病毒靶标的鉴定以开发新的抗病毒化合物。 虽然基于不同的分子克隆和不同的细胞系的其他强大的感染系统已经发展到今天,在这里我们描述了对应的感染JFH-1和JFH1衍生的病毒在我们的实验室生产病毒库存和持续感染细胞 文化。 我们还描述了用于确定病毒传播能力(多周期感染)以及解剖早期和晚期HCV感染(单周期感染)的实验设置。
