Mapping regulatory factors by immunoprecipitation from native chromatin.
Occupied Regions of Genomes from Affinity-purified Naturally Isolated Chromatin (ORGANIC) is a high-resolution method that can be used to quantitatively map protein-DNA interactions with high specificity and sensitivity. This method uses micrococcal nuclease (MNase) digestion of chromatin and low-salt solubilization to preserve protein-DNA complexes, followed by immunoprecipitation and paired-e...
متن کاملNative chromatin immunoprecipitation.
Native chromatin immunoprecipitation refers to a method that allows for identification and quantification of DNA that is associated with specific chromatin proteins without altering the structure of these proteins. The method has been used with great success in the past and has some advantages over the more widely used cross-linking chromatin immunoprecipitation. We describe here a protocol tha...
متن کاملChromatin immunoprecipitation on native chromatin from cells and tissues (PROT22)
In cells and tissues, the histone proteins that constitute the nucleosomes can present multiple post-translational modifications (Luger & Richmond, 1998), such as lysine acetylation, lysine and arginine methylation, serine phosphorylation, and lysine ubiquitination. On their own, or in combination, these covalent modifications on the core histones are thought to play essential roles in chromati...
متن کاملMapping chromosomal proteins in vivo by formaldehyde-crosslinked-chromatin immunoprecipitation.
Gene regulation is a complex process. Numerous factors appear to be required for the accurate temporal and spatial regulation of each gene. Often these factors are assembled into multiprotein complexes, contributing to specific gene regulation events. Understanding how all these factors are organized in the chromosome and how their function is regulated in vivo is a challenging task. One of the...
متن کاملFast chromatin immunoprecipitation assay
Chromatin immunoprecipitation (ChIP) is a widely used method to explore in vivo interactions between proteins and DNA. The ChIP assay takes several days to complete, involves several tube transfers and uses either phenol-chlorophorm or spin columns to purify DNA. The traditional ChIP method becomes a challenge when handling multiple samples. We have developed an efficient and rapid Chelex resin...
