    Histone modification ChIP-seq on Arabidopsis thaliana Plantlets
    Authors:  Juan S. Ramirez-Prado, David Latrasse and Moussa Benhamed, date: 11/05/2021, view: 1663, Q&A: 1
    [Abstract]

    Characterizing the molecular mechanisms regulating gene expression is crucial for understanding the regulatory processes underlying physiological responses to environmental and developmental signals in eukaryotes. The covalent modification of histones contributes to the compaction levels of chromatin, as well as the recruitment of the

    Assessing the in vitro Binding Specificity of Histone Modification Reader Proteins Using Histone Peptide Arrays
    Authors:  Mark W. Soo and Arneet L. Saltzman, date: 09/20/2021, view: 1128, Q&A: 0
    [Abstract]

    In the field of chromatin biology, a major goal of understanding the roles of histone post-translational modifications is to identify the proteins and domains that recognize these modifications. Synthetic histone peptides containing one or more modifications are a key tool to probe these interactions in pull-down assays with recombinant proteins

    Simplified Epigenome Profiling Using Antibody-tethered Tagmentation
    Authors:  Steven Henikoff, Jorja G. Henikoff and Kami Ahmad, date: 06/05/2021, view: 3184, Q&A: 0
    [Abstract]

    We previously introduced Cleavage Under Targets & Tagmentation (CUT&Tag), an epigenomic profiling method in which antibody tethering of the Tn5 transposase to a chromatin epitope of interest maps specific chromatin features in small samples and single cells. With CUT&Tag, intact cells or nuclei are permeabilized, followed by successive

    Bioinformatic Analysis for Profiling Drug-induced Chromatin Modification Landscapes in Mouse Brain Using ChlP-seq Data
    Authors:  Yong-Hwee Eddie Loh, Jian Feng, Eric Nestler and Li Shen, date: 02/05/2017, view: 9698, Q&A: 0
    [Abstract] Chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-seq) is a powerful technology to profile genome-wide chromatin modification patterns and is increasingly being used to study the molecular mechanisms of brain diseases such as drug addiction. This protocol discusses the typical procedures involved in ChIP-seq data ...
