    [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

    DNase I Chromatin Accessibility Analysis
    Authors:  Brook S. Nepon-Sixt and Mark G. Alexandrow, date: 12/05/2019, view: 2541, Q&A: 0
    [Abstract] Chromatin consists of compacted DNA in complex with proteins and contributes to the organization of DNA and its stability. Furthermore, chromatin plays key roles in regulating cellular processes such as DNA replication, transcription, DNA repair, and mitosis. Chromatin assumes more compact (inaccessible) or decondensed (accessible) conformations ...
    Determination of Chromatin Accessibility in Drosophila Midgut Enterocytes by in situ 5mC Labeling
    Authors:  Eliya Bitman-Lotan, Hector Rincon-Arano, Gal Raz and Amir Orian, date: 11/20/2019, view: 1955, Q&A: 0
    [Abstract] Regulation of gene expression involves dynamic changes in chromatin organization, where in many cases open chromatin structure correlates with gene activation. Several methods enable monitoring changes in chromatin accessibility, including ATAC-seq, FAIRE-seq, MNase-seq and DNAse-seq methods, which involve Next-generation-sequencing (NGS). ...
    ATAC-seq on Sorted Adult Mouse Neurons
    Authors:  Erin A. Clark, Yasuyuki Shima and Sacha Nelson, date: 10/05/2019, view: 3741, Q&A: 0
    [Abstract] Transcription regulation is a key aspect of cellular identity established during development and maintained into adulthood. Molecular and biochemical assays that probe the genome are critical tools in exploring mechanisms of transcription regulation and cell type identity. The mammalian brain is composed of a huge diversity of cell types with ...
