Zymo-Spin™ ChIP Kit 货号：A-D5209
背景资料：The field of epigenetics has grown tremendously over the past several decades. Studies have shown that chromatin modifications, DNA methylation, and DNA hydroxymethylation play critical roles in the regulation of gene expression, gene silencing, protein-DNA interactions, and other cellular processes. Dysregulation of epigenetic modifications can contribute to developmental abnormalities, neurological disorders, and even cancer.
Chromatin immunoprecipitation (ChIP) is the prevailing method used for the study of protein-DNA interactions and the dynamics of epigenetic modifications. ChIP facilitates the identification of regions of the genome associated with a specific protein. The Zymo-Spin™ ChIP Kit from Zymo Research provides a streamlined ChIP procedure for investigating protein-DNA interactions that have been “fixed” in their natural state and can be used to effectively identify binding sites for transcription factors, co-factors, and other DNA regulatory proteins
产品描述：Briefly, this ChIP protocol involves covalent cross-linking of protein-DNA complexes with formaldehyde followed by cell lysis and chromatin shearing. A ChIP-grade antibody (user supplied) is used with Protein A magnetic beads to immunoprecipitate the protein-DNA complexes of interest. Following reverse crosslinking, RNase A and Proteinase K treatments, the DNA is eluted in a minimal volume of buffer using a unique micro-elution spin column, eliminating the need for messy precipitations. The protocol has been optimized for efficient crosslinking, shearing, and immunoprecipitation regardless of the mammalian cell type. Additionally, eluted ChIP DNA is ideal for end point PCR, quantitative PCR, ChIP-Seq library preparation, and Next-Gen sequencing-based applications.

关于5-hmC
5-hmC是近年来在动物组织中发现的，由胞嘧啶修饰而来。5-hmC在表观遗传学上的功能可能与5-甲基化胞嘧啶(5-mC)不同。尽管到现在为止还不确知其功能，有研究者猜测它在调控基因的表达与关闭过程中起着重要的作用。5-mC的发现让我们不得不重新评估DNA甲基信息，也不得不监测人类的健康组织和病理组织之间5-mC相对分布的差异。在EPI公司的MethylFlash技术之前，我们还没有发现任何直接的常规方法来检测5- hmC,以及区分5-hmC和5-mC
5-hmC 和 5-mC的区别
时下常用的DNA甲基化分析方法包括限制内切酶酶切和亚硫酸氢盐或MeDIP介导的MS-PCR和测序，这些技术都不适合用来检测5-hmC，因为它与5-mC事实上很难用这类方法区分开来。为了解决这个问题，EPIk研制了MethylFlash羟甲基化DNA定量试剂盒(荧光法)。本试剂盒提供了一种很经济的方法来检测5-羟甲基化胞嘧啶，并且区分5-hmC, 5-mC, 和 C，使得研究者能够重新评估他们的DNA甲基化信息，也能够在新样品中寻找DNA羟甲基化。 |
