下面我将从多个角度来解释re-chip实验的步骤。 1. 样品准备,首先,需要准备实验所需的细胞或组织样品。这些样品需要经过交联来固定蛋白质与染色质的相互作用,并且需要进行细胞核的裂解以释放染色质。 2. 共价交联,接下来,样品需要进行共价交联,通常使用甲醛来交联蛋白质与染色质。这有助于固定它们的相互作用状态,使...
re-ChIP技术是在单一ChIP的技术上,延伸的一种新型双重免疫共沉淀技术。它的基本原理是在活细胞状态下把细胞内的蛋白质和DNA交联,超声波将其随机切断为一定长度范围内的染色质小片段,然后用所研究的目的蛋白质特异性抗体免疫沉淀蛋白质-DNA复合体,从而特异性地富集目的蛋白结合的DNA片段。它是在第一次ChIP洗脱样品的...
ChIP有很多种变体,比如说和染色质构象结合的ChIA-PET,而Re-ChIP指的是对一个抗体富集的染色质片段用另一个抗体进行再富集。这种方法的目的在于捕捉两种抗原都结合的染色质。因为分开ChIP损失了这一信息。但Re-ChIP缺点是产率极低,涨落极大。不过无论如何ChIP的可定量性一直是一个问题。 在这篇文章中,研究者使用...

re-chip /riːˈtʃɪp/ verb (re-chipped, re-chipping) [transitive] to put a new computer chip into a piece of electronic equipment such as a mobile phone or a computer games machine so that you can use software that you are not supposed to use, or use a service that you ...

In Re-ChIP-IT, following formaldehyde fixation of the cells, chromatin is sheared and incubated with the first antibody, and antibody-bound protein/DNA complexes are precipitated through use of magnetic Protein G-coated beads. The captured “First ChIP” chromatin is then eluted with a specialized...

3 reagents required Re-ChIP stands for sequential chromatin immunoprecipitations with two antibodies to study the simultaneous presence of two proteins, or different histone modifications in the genome sequence of interest. We perform elution with Elution Buffer (contains 1% SDS). We found it crucial...
