[Abstract]  Chromosome conformation capture (3C) techniques are crucial to understanding tissue-specific regulation of gene expression, but current methods generally require large numbers of cells. This protocol describes two new low-input Capture-C approaches that can generate high-quality 3C interaction profiles from 10,000-20,000 cells, depending on the resolution used for analysis. [摘要]  染色体构象捕获(3C)技术对于理解基因表达的组织特异性调节是至关重要的,但是目前的方法通常需要大量的细胞。 该协议描述了两种新的低输入Capture-C方法,根据用于分析的分辨率,可以从10,000-20,000个细胞生成高质量的3C相互作用谱。

【背景】3C技术在调查调控元件之间的核组织和结构相互作用与基因活性之间起关键作用(Dekker等人,2002)。 由于这些相互作用是高度组织特异性的,3C定义的纯化细胞群进行3C实验是至关重要的。

3C技术的一个主要局限性是所需要的大量细胞:目前的方法使用了10万到10万个细胞(Davies等人,2017)。 这些数字中不包含许多原发性组织和稀有细胞群。 因此,我们开发了两种新的低输入Capture-C方法,可以从最大分辨率的〜20,000个细胞(单独的DpnII片段)和使用基于开窗分析的约10,000个细胞产生高质量的相互作用谱(Oudelaar等人 。,2017)。

Plant Sequence Capture Optimised for Illumina Sequencing

[Abstract]  Plant Sequence Capture is used for targeted resequencing of whole exomes (all exons of a genome) of complex genomes e.g. barley and its relatives (Mascher et al., 2013). Sequencing and computing costs are significantly reduced since only the greatly enriched and gene-coding part of the barley genome is targeted, that corresponds to only 1-2% of the entire genome. Thus, applications such as genetic diversity studies and the isolation of single genes (“cloning-by-sequencing”) are greatly facilitated. Here, a protocol is provided describing the construction of shotgun DNA libraries from genomic barley DNA for sequencing on the Illumina HiSeq/MiSeq systems. The shotgun DNA sequencing libraries are hybridized to an oligonucleotide pool (Exome Library) encompassing the whole ... [摘要]  植物序列捕获用于复杂基因组(例如大麦及其亲属)的整个外显子(基因组的所有外显子)的靶向重测序(Mascher等人,2013)。测序和计算成本显着降低,因为只有大麦基因组的大量富集和基因编码部分被靶向,其仅对应于整个基因组的1-2%。因此,大大促进了诸如遗传多样性研究和单个基因的分离("通过测序克隆")的应用。这里,提供了描述来自基因组大麦DNA的Shotgun DNA文库的构建以在Illumina HiSeq/MiSeq系统上测序的方案。鸟枪DNA测序文库与包含大麦整个外显子组的寡核苷酸池(Exome Library)杂交。外显子组库作为包含生物素化探针(Roche/NimbleGen)的液体阵列提供。随后,使用链霉亲和素包被的磁珠对与Exome文库杂交的基因组鸟枪DNA片段进行亲和纯化。捕获的文库被PCR扩增和测序,使用高通量短读序列合成
